And envy is the organizing principle of socialism.
Socialists wouldn't stand a chance with the argument that the State will take the fruit of your labor and distribute it according to the needs of the State. However, many people are attracted by the argument that the State should take the fruit of another's labor and distribute it to them.
Oh, it’s more devious than having the State take it from another and give it to me,
it’s that I (if I were a liberal) can feel righteous by advocating that the State take from person A and give to “needy” person B.
