In the work that’s essentially the gold standard in the field, it’s concluded that for roughly 70% of the population – the lower 70% on the wealth/income scale – they have no influence on policy whatsoever. They’re effectively disenfranchised. As you move up the wealth/income ladder, you get a little bit more influence on policy. When you get to the top, which is maybe a tenth of one percent, people essentially get what they want, i.e. they determine the policy. So the proper term for that is not democracy; it’s plutocracy.
Inquiries of this kind turn out to be dangerous stuff because they can tell people too much about the nature of the society in which they live. So fortunately, Congress has banned funding for them, so we won’t have to worry about them in the future.
