So what? There is still lot of variation on how much you have to spend on that degree. Consider:
Student A:
Spends high school getting good grades and receiving an allowance from his parents.
Attends an expensive private school.
Takes out hefty loans to pay for school and the same standard of living he enjoyed with his parents.
Has little financial help from his parents who figure that the student loans cover everything.
Graduates with $70,000 in debt, unrealistic ideas about the standard of living he "needs", little understanding of how to manage his finances and plenty of fear to make him avoid the problem, and is unable to afford either that standard of living or his debt repayments.
Spirals into deep debt for many years.
Student B:
Works part time through high school and has money saved for tuition.
Takes out a small student loan to cover remaining expenses.
Continues to work weekends so has a small amount of cash flow.
Goes to a cheaper state university and gets used to the idea of
living on rice and beans and keeping their clothes in milk crates.
Graduates with perhaps $10,000 in debt, a good handle on their finances, an inexpensive lifestyle, and a solid plan for paying off the debt within a few years.
Continues to wealth and prosperity.
How much poverty and bad decisions could be prevented if more students took route B instead of route A? Do you still think it doesn't matter if we teach them financial independence or not?
