According to a new study, between 2008 and 2012 unemployment insurance alone prevented about 1.4 million foreclosures. From Wonkblog (my emphasis):
...the housing crisis begat an unemployment crisis that begat an even worse housing crisis. Only the government could stop this vicious circle. It had to help the unemployed so they could stay in their homes. And it had to stabilize housing — along with the rest of the economy —so more people wouldn't lose their jobs.
