Let's try this out.
Basically it's lowering home interest rates to 4% so people can refinance their mortgages. Getting a 4% rate would immediately help the many, many people out there who are making payments on their mortgages and didn't buy more house than they could afford. We'd have more money every month which could lead to more spending which could help the economy. In times of economic trouble, let's not just help those who are totally screwed, but also those who are teetering on the edge.
