Austan Goolsbee advises for low/middle income tax relief

He says:

But if subprime housing morphs into a credit crunch, it’s not clear that just lowering rates will address the problem.
If you can move quickly enough, I think tax relief for low/middle income mortgage holders would certainly be in order as a way to lessen the credit crunch damage of the housing market–the benefits would multiply up because of the leverage in the same way the losses are getting magnified now. If the economy continues to slow and the housing troubles actually morph into a crisis of consumer confidence, and direct tax relief for middle and working class folks would be the order of the day.

How much more relieved can we get?
