The most famous socialist was Judas Iscariot.
When Mary, the sister of Lazarus, anointed Jesus with costly perfume just days before the crucifixion, Judas lectured her and said, “Why wasn’t this perfume sold and the money given to the poor?”
Notice that Judas put on a show of caring for the poor - even though the money was Mary’s, not his!
The motives of Judas, John 12:6 tells us, were corrupt and self-centered - and Jesus responded with a stinging rebuke.
“This he said, not that he cared for the poor; but because he was a thief, and had the bag, and bare what was put therein.”
Which gets to the heart of socialism:
Envy disguised as altruism.
Judas was not concerned about the poor, he wanted money.
That sounds familiar. :-)
