ELI5 what is the student debt bubble and what will happen when it falls apart?
gpt
The cost of college is rising much faster than wages, so people are taking on debt to pay for the rising cost. It is becoming common to have over 100k in debt when completing a 4 year degree. Due to this many groups are getting involved to get a piece of the debt pie, which is driving up prices. 

The fallout will be similar to the housing bubble bursting. Many institutions will be forced to close as they have no money and lots of people will have their lives ruined.
