A paper from 2014 by Martin Gilens and Bejamin Page shook the bedrock of the American democracy by showing quite decisively that the likelihood of a policy being adopted in Congress is almost entirely unrelated to the amount of preference that citizens have for the policy. The preferences of economic elites (rich folks) and special interest groups (generally representing businesses) are far more likely to be enacted by Congress. The wedge in American politics may explain this perfectly.
