The great evil of our Senatorial system is that industries can buy, on the cheap, Senators from sparsely populated states. Buying the Senator from Montana costs only a fraction of what it costs to buy the Senator from New York. In this way, industries can block needed change by buying three or four Senators, or even, if needed, ten.
The only way out of this is to restore simple majority rule in the Senate, making it more expensive for industries to buy enough Senators. Certainly, requiring them to buy 11 Senators will not bankrupt them, but it would be a good deal more expensive for them than buying one or two, as they have done with Senator Baucus.
