Your assumption rests on the notion that the government = everyone, and that the people in power aren't focusing that money toward their own pockets. I'm not aware of a Socialist government that has ever existed that did anything but line their own pockets while the people starved and went without.

Mao's China, Lenin & Stalin's USSR, old Vietnam, Cambodia under Pol Pot, Hugo's Venezuela, Fidel's Cuba, North Korea. It's the same story every time.

Even in a democracy you'd be lucky if that were even 10% true. In a socialist government, even more unlikely.
