Why U.S. Public Education Became So Expensive

This chart illustrates a major driver behind the rising costs of U.S. public education. Between 1970 and 2018, public school enrollment increased by 11.3%, rising from 45.9 million to 51.1 million students. During the same period, the teaching workforce expanded at a much faster rate, growing from 2 million to 3.17 million. This change lowered the student-teacher ratio from 23:1 to 16:1.

The most significant shift occurred outside the classroom. Non-teaching personnel expanded rapidly and eventually outnumbered teachers. While this category includes essential roles like aides, counselors, and librarians, every additional position adds salaries, benefits, and administrative overhead to the payroll. Because staffing growth dramatically outpaced student enrollment, the resulting budget pressure remains a direct consequence of a vastly expanded school system.

Your brain may keep learning even when you are unconscious

Scientists recently recorded neural activity in the hippocampus of seven patients under general anesthesia and found something strange: the brain was not just passively hearing sounds. It was still learning patterns. In one experiment, hippocampal neurons became better at detecting unusual tones among repeated sounds over just a few minutes.

In another experiment, patients under anesthesia listened to speech. Their hippocampal neurons responded to word frequency, parts of speech, and semantic categories, and even carried information about what kind of word might come next in a sentence.

Clearly, nobody is learning a new language while knocked out, but the takeaway is clear: even when consciousness is completely switched off, the brain keeps mapping out the outside world.

How strict usage targets turn corporate AI into a numbers game

The Financial Times recently uncovered a hilarious example of what "AI transformation" actually looks like inside Amazon. Employees say they are being pushed to use internal AI tools constantly, even when the practical benefit is anyone's guess. So, to keep up appearances, some developers started spinning up unnecessary software agents and creating fake tasks. The goal isn't to write better code; it's simply to burn through AI tokens so their usage looks high on company dashboards. It’s not about better work - it's just about visible activity.

Amazon claims there is no company-wide leaderboard and that these numbers don't affect performance reviews. But the reality is simpler than that. Once leadership drops a target like "80% of developers must use AI every week," and everyone can see the token metrics on a screen, the pressure is on. Middle managers don't need an official corporate goal to understand which number they’re supposed to inflate.

This is the classic irony of corporate metrics. If you measure productivity, people will give you productivity theater. If you measure AI adoption, they will give you AI adoption theater. The bot runs, the charts go up, and the manager gets a nice story to pitch to the higher-ups.

The ocean is still controlled by a few countries, just not the same way

Back in the 1890s, British shipyards launched about 80% of the world's shipping tonnage. The industry looked completely unstoppable even after World War II, and for a brief window, Britain actually built more ships than the rest of the planet combined.

The downturn happened because the global industry evolved faster than British firms could adapt. Shipping shifted toward massive production facilities that relied on heavy cranes and tight schedule management. Instead of building custom vessels, competitors focused on huge tankers assembled from prefabricated parts. The traditional British approach relied on small sites and the specialized skills of individual laborers. This worked well for smaller, bespoke vessels, but it became a liability when the global market demanded massive industrial scale.

The decline happened fast. Britain held 57% of global tonnage in 1947, but that share dropped to 17% a decade later. The figure slipped below 5% by the 1970s and fell under 1% by the 1990s. In 2023, the country failed to produce a single commercial ship.

The interesting part is that global maritime power remains highly concentrated, though it looks different now. Greece, China, and Japan own over 40% of the global fleet by capacity, while the top ten nations control roughly two-thirds of the total volume.

Shipbuilding became a complex game of massive capital investments and giant industrial systems. A country that succeeded through flexible manual labor lost its edge when the market rewarded heavy infrastructure and strict corporate engineering.

Six billion people are online, but the internet is still not equally global

About three quarters of humanity, roughly six billion people, is now plugged into the global web. In one sense, this is a real triumph for the globalists, technocrats, telecom builders, undersea cables, cell towers, and cheap smartphones that spent decades pulling the planet online. But behind the optimistic charts, the old structure of inequality is still there: in high-income countries, internet access is almost universal, around 94%, while in low-income countries it is still only about 23%. So the internet has become global, but not evenly global. For billions of people on the periphery, access to the digital world still depends on the same basic things: electricity, infrastructure, money, devices, and enough stability for “being online” to matter in everyday life.

Solar is no longer just adding some green electricity on top of the old power system. In 2025, clean sources covered all the growth in global electricity demand, and solar alone provided about 75% of that increase. That is a pretty sharp break from the 2000s and early 2010s, when rising electricity demand usually meant more fossil generation.

That is usually how old systems start losing ground. Not by disappearing overnight, but by losing the growth market first. If new electricity demand keeps being absorbed by solar, wind and other clean sources, fossil fuels stop being the default answer to growth. They become the old base that gets squeezed whenever clean power grows faster than demand.

As Erdoğan tries to ride the wave of economic turbulence, Ankara is going all in. Turkey’s inflated inflation, which peaked at around 75% year-on-year, and the renewed nervousness across the Middle East are forcing the country to radically rethink how it attracts capital. As the region’s familiar hubs no longer look quite as untouchable under the risk of further escalation, Turkey is preparing to cast itself as a new “safe hub” and compete with Dubai for capital, headquarters, and wealthy residents.

The Turkish lira has sharply weakened against the dollar over the past five years, and the government badly needs hard-currency inflows to cover its current account deficit. To capture some of the capital now looking at the region more nervously, the economic team is launching an unprecedented reform package. According to the official statement by Finance Minister Mehmet Şimşek, reported by Anadolu, Ankara is effectively trying to turn Turkey into one of the most aggressive tax havens in the region.

The incentives are hard for business to simply ignore. According to a detailed legal and tax breakdown by Evren Özmen CPA, international companies that move regional headquarters to Turkey will receive major tax breaks. For manufacturing exporters, the corporate tax rate is being cut to 9%, down from the standard 25%, while service exports will receive a 100% tax exemption.

But the biggest hunt is for digital nomads, wealthy residents, and rentiers. The proposed program gives new tax residents, those who have not lived in Turkey for the past three years, 20 years of tax freedom on income earned outside Turkey. Their inheritance tax would be reduced to a symbolic 1%.

In effect, we are watching Ankara’s old regional ambition merge with the logic of a new tax haven and ultra-capitalism. As the neighborhood becomes more unstable, Turkey’s parliament is preparing to package these bills, while the economic team hopes to turn its own inflationary nightmare into fuel for a leap forward. Turkey may not replace Dubai tomorrow. But the bid is already clear: to become a backup route for capital that still wants safety, but is starting to look for it outside the usual places.
