But wait, there's more. As part of the economic stimulus package, the federal government is promoting Build America Bonds, under which the Treasury pays 35% of the interest costs of project-related bonds issued by state and local governments. These BABs, as they're known, are taxable securities rather than being tax-exempt as normal state and local bonds are.

The BAB program has sharply reduced the supply of new tax-exempt muni bonds. Almost $40 billion of Build America Bonds have been issued since the program began in April, according to Bloomberg.

Chip Norton, a muni maven at Wasmer Schroeder & Co., says that by reducing the supply of new munis, Build Americas have been a major factor in driving down yields on one- and five-year triple-A munis to 0.5% and 2.3%, respectively, from 3.4% and 3.6% two years ago.

One day, the federal government won't be able to keep all these interest rates artificially low, as it's now doing. The Chinese government, our major financier, is growing restless. The dollar's falling sharply relative to other currencies is an ominous sign. If this problem accelerates, it will put pressure on the Fed to let interest rates rise to protect the dollar from a collapse.

But until rates go up, Wall Street will be chowing down on essentially free money, while fixed-income people living off their investments will have to eat into their capital, take more risk, or reduce their standard of living. A nice reward from their government for a lifetime of saving. Thanks for nothing, guys.
