I think the only way to solve this is in a deep and fundamental way is to strip congress of the power to make decisions that benefit corporations.
I realize that this sort of libertarianism is often viewed as "immature" or primitive. But ultimately I don't see how you can have, one the one hand, a congress powerful enough to do healthcare and financial reform, and on the other hand, be surprised when the same congress is successfully courted by financial interests. It seems to be an inevitable result.
That's not the only way. One alternate option is Futarchy. A less drastic one is implementing the top 3 or 4 pieces of model legislation at downsizedc.org.
