What he does, being a capable and honest male intellectual - also known, in the US, as a "leftist" or "man of the left" (if they are female, they are known as "feminists" rather than "leftists" for some reason) - is point to the consequences of having higher education entirely or largely funded by the wealthy or those borrowing to invest in their own wealth, rather than by its major beneficiaries.What he doesn't like, being a man of the left, is education being funded by its beneficiaries, rather than being paid for out of general taxation.
In classical economics this is called a "market distortion", and this kind of market distortion leads to underinvestment in the good or service.
Illustration: This is the centennial year of Norman Borlaug's birth, March 25 is the date, and it may be worth noting that the main funders of Borlaug's education - the taxpayers of Iowa, Minnesota, and the US, with the earnings of their world trade and agricultural emphasis - got enough return on their investment to cover the entire cost of the University he attended for everybody who has ever attended since, probably several times over.
And they will never have that kind of investment return again, because the Borlaugs of today have to make other arrangements - for their educations, and then for their lives. When Borlaug was faced with the choice of taking Dupont's offer to double his salary rather than chance a new and uncertain kind of crop breeding program in backwater Mexico for low pay, 75,000 dollars in grad school debt piling up interest did not figure into the decision.
