From Brewster Kahle’s blog:

A recent paper from Princeton evaluated of over 1700 federal government policy decisions made in the last 30 years and found “economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while average citizens and mass-based interest groups have little or no independent influence.” Therefore, according to this research, the vast majority of the population has little or no say in how the federal government makes policy decisions. Similarly discouraging is the economic analysis over the last 30 years that found that the increase in American wealth went to only the wealthiest 1% of the population, with the other 99% essentially staying even. Therefore, there has not been equal opportunity for economic success in the United States for the vast majority of the population.
