Democracy has a LOT of potential fatal flaws, with apathy either leading the list or darn close to it.
Democracy pretty muchs ends when The People realize they can vote for themselves money in the form of
any type of Government aid regardless what it is called (welfare, interest deduction, tax break, Social Security, etc.),
and then vote only for the politician willing to cater to their whim.
That's not democracy, that's addiction, and boy-oh-boy does this country have a LOT of addicts.
