Half the world's renting households spend more on rent than is considered healthy. According to the new UN-Habitat report, 44% of the planet's tenants pay more than 30% of their income on housing. You'd expect the whole weight to fall on poorer regions. But the gap between poor and rich turned out far smaller than expected. In Sub-Saharan Africa the share of rent-burdened households is the highest in the world, 55%, and the reasons are plain: low and irregular incomes, almost no formal rental supply, widespread informality. In Latin America and the Caribbean it's 48%. But in Europe and Northern America it's nearly the same: rent is out of reach for one renter in two, 50%. Western economies have essentially caught up with Latin America and sit right up against the African figures. The causes differ - the West runs into zoning rules, interest rates and expensive construction, while poorer regions run into informal economies and thin housing supply - but the strain that lands on the tenant's wallet comes out almost the same.

I keep seeing the same narrow script pushed on local subs like r/somerville or r/CambridgeMA — if Somerville just keeps aggressively upzoning and giving market-rate developers a blank check to build luxury boxes, prices will magically trickle down and fix our affordability crisis. This recent Morgan Stanley report blows that fantasy apart by showing housing is driven way more by national macroeconomic forces than by city council zoning maps.

Morgan Stanley's analysts explicitly say the US housing market is unlikely to ever return to pre-2022 affordability levels. They don't blame local zoning boards or NIMBYs for that. They point to massive systemic drivers instead: relentless household debt, broader cost of living inflation, and the lasting effects of the post-pandemic economic reset. That underscores how macro conditions, plus federal and state policies that actively subsidize institutional build to rent capital, dictate when developers build and when they sit on their hands far more than any local zoning tweak ever could.

Aggressive upzoning actually backfires by turbocharging these macro cycles. Here's how it plays out. When rates are rock bottom, wide open zoning lets private equity flood the market with cheap debt and bid land prices up to astronomical heights, locking in a permanently inflated cost baseline for the dirt under our feet. Then the second rates jump or the economy tightens, developers don't keep building just because zoning allows it. They freeze projects to protect their margins, choking off new supply right when prices should be softening and the market actually needs relief. Meanwhile carrying costs like interest, labor, materials, and insurance have structurally reset higher everywhere, and developers are paying a premium specifically for our limited geographic perks like proximity to the T, universities, and biotech. They're never going to voluntarily overbuild to the point of destroying their own asset values just because we changed a local zoning code.

If we want real affordability in Somerville we have to stop pretending local zoning tweaks are a silver bullet, even when studies get cited claiming it works (and often, that is not even what those cited studies show). All zoning reform does in this context is act as a multiplier and a distraction for Wall Street's capital cycles. We need direct public funding, real inclusionary mandates, and state-level intervention, not the delusion that corporate developers are going to build us out of a systemic national debt and housing affordability crisis.
