Who's buying our democracy? Wall Street financiers, the Koch brothers, and casino magnates Sheldon Adelson and Steve Wynn, among others. And they're doing much of it in secret. It's a perfect storm - the combination of three waves that are about to drown government as we know it. The first is the greatest concentration of wealth in America in more than a century. The 400 richest Americans are richer than the bottom 150 million Americans put together. The trend started 30 years ago, and it's related to globalization and technological changes that have stymied wage growth for most people, trickle-down economics," ... tax cuts and the steady decline in the bargaining power of organized labor. The second is the wave of unlimited political contributions, courtesy of ... one of the worst decisions in Supreme Court history, Citizens United vs. Federal Election Commission, the 2010 ruling that held that corporations are people under the First Amendment, [meaning] that virtually any billionaire can contribute as much to a political campaign as he wants. The third is complete secrecy about who's contributing how much to whom. Political fronts posing as charitable, nonprofit "social welfare" organizations ... don't have to disclose their donors. As a result, outfits like the Chamber of Commerce and Karl Rove's Crossroads GPS are taking in hundreds of millions from corporations that don't even tell their own shareholders what political payments they're making. Separately, any one of these three would be bad enough. Put the three together, and our democracy is being sold down the drain.
