Not to discount the severity of the student loan problem, but the market is really not large enough to cause the next big crash. For some perspective, pre-crisis mortgage debt was almost two-thirds of GDP whereas student loans are still a much smaller portion. Mortgages on hugely inflated home prices also sucked up a huge portion of incomes in 2007. Add in the systemic infection of credit default swaps and junk mortgage-backed securities on Wall Street and you had the Crash. Hopefully we&#x27;ll wisen up well before student loans get to that point.
