You just happened to pick a corrupt place to live. I know a few rich people and none of them attend political events. One friend employs over 150 people...they do drive the economy. For those who do play the system, is that their fault or the fault of the politicians who let it be known that they can be bought?
Buying a politician is not really in the spirit of free market capitalism. You buy the politician to evade the harsh realities of the marketplace.
