Government by a well-to-do minority
At The Atlantic, Lawrence Lessig explains that those who run America, those on both the left and the right, are much fewer than the 1%:
[W]e give the tiniest fraction of America the power to veto any meaningful policy change. Not just change on the left but also change on the right. Because of the structure of influence that we have allowed to develop, the tiniest fraction of the one percent have the effective power to block reform desired by the 99-plus percent. Yet by "the tiniest fraction of the one percent" I don't necessarily mean the rich. I mean instead the fraction of Americans who are willing to spend their money to influence congressional campaigns for their own interest. That fraction is different depending upon the reform at issue: a different group rallies to block health-care reform than rallies to block global warming legislation. But the key is that under the system we've allowed to evolve, a tiny number (with resources at least) has the power to block reform they don't like. A tiny number of Americans -- .26 percent -- give more than $200 to a congressional campaign. .05 percent give the maximum amount to any congressional candidate. .01 percent give more than $10,000 in any election cycle. And .000063 percent -- 196 Americans -- have given more than 80 percent of the super-PAC money spent in the presidential elections so far.
