Its funny because the cartoon's author can get stupid people to believe this is the case.
No, son, it's quite accurate. Socialists always say it's "our" wealth, collectively, that needs redistribution -- but tend to be rather tight-fisted with their own money (not much on charity giving, etc, in contrast to conservatives). Just ask your high priest, arch-socialist Bernie Sanders, which of his three homes he's going to sell off to redistribute to the poor.
