Is U.S. Democracy or Plutocracy?

.
Among others Gerald Celente argues that the United States is a plutocracy not a democracy.

If we posit that a plutocracy means that wealth influences government, there may be a point here.

Consider the $1 trillion dollar candidate elected this past November. Consider the billions spent by businesses and foreign governments to influence legislation both in Washington DC and fifty state capitals.

And don't forget to consider that the votes of citizens are influenced in large part by the perceived amount of "government money" which will be spent on their personal behalf.

The real problem it seems to me is that plutocracy has a natural path of decline ... to a kleptocracy, or 'government by thieves.'

When will we citizens take back control of our own government?
