Are Corporations a Threat to Democracy?

[Idaho]

Is this how it is in the U.S.? Obviously not, because no matter what, the politicians are still chosen by the people which preserves a connection between a politicians and his/her constituents and prevents a total override from corporations from being able to turn the country back into the Gilded Age, such a drastic decrease in the standard of living for peoples lives will get everyone angry and politicians will need to actually work for them (or at least pretend to) to make sure everybody is not thrown overboard so to speak. But nevertheless, when the people are happy and content and the economy is doing well and everyone is distracted by their bread and circuses, are the politicians maintaining the will of the people?

Throw in a full stop now and again would you?

Your politicians aren't chosen by the people. Your politicians are picked from a well vetted and controlled shortlist. Those who can secure corporate backing are are the only ones allowed on the two big tickets.
