Government backed student loans are a scheme to indebt eighteen year olds before they start their lives. Not everyone needs to go to college. Trades have a better ROI for the average person nowadays. We're obsessed with college in the states for some reason.
More often than not the loans wouldn't be granted because there wouldn't be any collateral and the student could simply declare bankruptcy and get rid of the debt. College would have to be cheaper so people could actually afford it.
I don't know why you're getting down voted, I completely agree, student loans shouldn't be a thing, we should provide education to those who want it for free, like the rest of the civilized world.
