Back in 2003 Warren studied consumer bankruptcy in The Two Income Trap. She discovered that overextended borrowers weren't being driven into bankruptcy due to unwise spending on luxuries, but in an effort to buy homes in better school districts. She says that the strongest predictor of bankruptcy is having a child and trying to educate that child.
The solution she suggested back in 2003? Improve public school districts to reduce the stark disparity between the schooling you can receive in different towns.
(It is pretty nutty that people spend all sorts of money on a house as a proxy for spending money on education. It has also occurred to me that what really ended the Great Depression was not the New Deal, but the GI Bill. Maybe we should pouring our stimulus into schools and students.)
