The Financial Times is running an excellent article on the a long term (and permanent) solution to our problem of economic growth:

One of the biggest problems that led to the bubble was tax policy.  We more or less subsidized the bubble:

"Another option is to eliminate – or limit – Americans’ ability to reduce their taxable income by deducting mortgage interest payments. This has been criticized because it offers a strong incentive for people to buy homes even when they cannot afford them, which was one of the root causes of the financial crisis."

Bingo.  The government should have no involvement in the private sector to begin with.
