Yes, I think the best tool against these trends is education. PR machines cannot work in the open. Politicians cannot do dirty deals in the open. This Enron thing won't amount to much in the long run, for it is millionaires trying other millioinaires, but at least the general public has been that much informed about the way things get done in the higher reaches of corporations and the government.
The more people know what's really happening, and that means getting information beyond the U.S. media machine, the more they will be disgusted and the closer we will get to actual, meaningful reform.
