He lost my respect when he started preaching that student loans weren't debt!
Well, you have to make repayments, you're charged high interest rates, so that sounds like a debt to me!
Saying it's not debt is only relevant for those who'll never earn enough to make regular repayments. Or to those who'll be exceedingly high earners who'll pay it off pretty quickly and thus not incur decades of added interest!
It's terrible advice for those likely to earn over the threshold for most of their working life, but not high enough to pay off the loans, so they'll be making minimum payments all their working lives and still not pay off the debt once interest has been added every year.
