The 150 hour requirement was nominally introduced to cull CPA candidate numbers. But that was 20%. The other was a lobbying victory from The College Industrial Complex. Otherwise, why not simply make the CPA exam harder or increase the required number of experience years?
Rather than instructing people to go through an additional year of school ...and debt for what? The Academic lobby and representation on the AICPA's board.
In fact, there shouldn't even be a College degree requirement. If you can pass the CPA exam that should be the extent of your CPA Academic program. That's it. The real debate should be around experience (which I think should be closer to 5 years than 1 year).
