The great danger of any democracy was recognized at the founding of the Constitution: that the people would eventually discover that they could support themselves by taking money from the public treasury. And when this happened, the country would be at an end, or rather, it would collapse into something quite different than the constitutional republic envisioned.
We are at that point now. When 51% of the voting population comes to believe that it can enslave the other 49 or less percent, we have the Tyranny of the Majority. Those who can will leave and the rest will degenerate into a disordered kleptocracy, with Peter robbing Paul and then Paul robbing Peter in-turn, until some tyrant promises to fix everything and we vote him in...once. Welcome to Fascism!
