From NYTimes.com:
“Tonight, I propose a new tax cut for  homeownership that says to every middle-income working family in this  country, if you sell your home, you will not have to pay a capital gains  tax on it ever — not ever.”
— President Bill Clinton, at the 1996  Democratic National Convention
Ryan J. Wampler had never made much money  selling his own homes.
Starting in 1999, however, he began to  do very well. Three times in eight years, Mr. Wampler — himself a  home builder and developer — sold his home in the Phoenix area, always  for a nice profit. With prices in Phoenix soaring, he made almost $700,000  on the three sales.
And thanks to a tax break proposed by  President Bill Clinton and approved by Congress in 1997, he did not  have to pay tax on most of that profit. It was a break that had not  been available to generations of Americans before him. The benefits  also did not apply to other investments, be they stocks, bonds or stakes  in a small business. Those gains were all taxed at rates of up to 20  percent.
The different tax treatments gave people  a new incentive to plow ever more money into real estate, and they did  so. “When you give that big an incentive for people to buy and sell  homes,” said Mr. Wampler, 44, a mild-mannered native of Phoenix who  has two children, “they are going to buy and sell homes.”
 
By itself, the change in the tax law  did not cause the housing bubble, economists say. Several other factors  — a relaxation of lending standards, a failure by regulators to intervene,  a sharp decline in interest rates and a collective belief that house  prices could never fall — probably played larger roles.
