Some crats don't want to take your wealth because stealing is morally wrong. Instead they will settle for destroying it. Arguably destruction is morally more repugnant than stealing but they don't see it that way. Their motive is to reduce their painful feelings of envy. Swapping for painful feelings of guilt does not work for them. So they need 1) poor people as a socially acceptable excuse to take your stuff (there are always poor people), and 2) a bloated government to shred 50% of the wealth right off the top. Of course the government beast willing cooperates. Everybody wins but you, the mark.
Take a look at Cuba or North Korea or any of the commie states: 99% of the population suffer and live in horrible conditions as slaves, 1% live in luxury as part of the ruling class oligarchy.
It never starts out that way though, the poor are sold on the utopian vision and they get free stuff for a while. Then they keep voting for more until the money runs out..
