For people who can't balance a budget, your Congressmen have some amazing business savvy.
A new report shows that from 1985-2001, members of the House of Representatives invested in stocks and out performed the market by 6% per year. 6% a year, every single year, is a healthy return, but 6% over the market is down right amazing.
An early study, conducted by the same group of professors in 2004 found that members of the Senate did even better, about 11% above the market.
Both parties did well, but Democrats fared slightly better than Republicans. Maybe because they're smarter, maybe because they spend more time analyzing what corporations do instead of just bowing down to their corporate overlords, or maybe because they're he exact same types of cheats the Republicans are, but just happened to be in power more of those years than the Republicans were.
There are no laws against Congressmen using "insider" information that comes to them through the course of their jobs, such as who will land a lucrative contract, or which way the regulation of incandescent light bulbs will go.
