In other words the market effects of guaranteed student loans that permited colleges/universities to charge any tuition fees they want and still have an endless supply of student with the funds to pay. Baby boomers can't imagine graduating with the equivalent of a mortgage payment and the reality of a non existent job market that might put them in a financial position to payoff their student loans much less pursue the American dream (house, car, kids).
Meanwhile culturally we have a media that pushes the narrative of 4% unemployment; that young people don't want to own a car; young people don't want to own a house; and young people don't want to get married and have families. The whole thing highlights US culture from the individual to the collective willing to lie/embellish finances, which prohibits anyone from having honest conversations about guaranteed loans; actually costs of school; lack of jobs; non existent wage increases since the 80's...it's the culture of lying/masking finances and a debt fueled economy that lead to housing collapse and eventually will lead to a collapse in the student loan market.
The culture surrounding education in this country is not rational. It's a soup of optimism, hope, preconception, ignorance, and classism, along with the avarice of those in the educational establishment that prey on the foregoing.
