“Democracy is the theory that the common people know what they want, and deserve to get it good and hard.”
-- H.L. Mencken
Is the US two party system democracy working as intended?
We don't actually live in a representative democracy, we live in a constitutional republic — with things like caps on representatives, the electoral college and gerrymandering, your vote is likely worth a lot less than someone's vote in Ohio or Alaska.
Shoot yourself in the head or cut your wrists with a knife?
Those are your choices. Choose freely!
Calling the USA a democracy when you don't even have a right to get a work permit to actually vote is insane.
