Nothing? That's how it's worked in literally all functioning democracies. The purpose of any government, democratic or not, is to benefit its constituents. If it doesn't do that, we have a moral obligation to destroy the tyrants. Those benefits range in their tangible value, from hard to quantify things, like establishing public expectations of behavior (laws), to easy to quantify (subsidies like wellfare, farming subsidies, etc).

I'm truly baffled by your take that seems to insist that helping the needy somehow makes you moreso a slave to the government than the whole monopoly on legitimate use of force thing.
