Percentagewise, About Half As Many Of Today's College Grads, Compared To 1970 Grads, Are From The Bottom Income Quartile

From The Wall Street Journal, "Richard Vedder: The Real Reason College Costs So Much: The expert on the economics of higher education explains how subsidies fuel rising prices and why there's a 'bubble' in student loans and college enrollment." by Allysia Finley:

Today, only about 7% of recent college grads come from the bottom-income quartile compared with 12% in 1970 when federal aid was scarce. All the government subsidies intended to make college more accessible haven't done much for this population, says Mr. [Richard] Vedder. They also haven't much improved student outcomes or graduation rates, which are around 55% at most universities (over six years).
