Jesus never took one penny from anyone to cure diseases. He demands that we follow Him willingly. There is nothing willing about socialism.

Clearing merchants from the temple has nothing to do with capitalism. Capitalism is nothing but the freedom to buy, sell, trade, and associate as the involved parties see fit. Clearing the merchants was to remove thieves and swindlers from a place of worship.

Jesus said that the rich have a hard time getting to heaven because they have something other than Him to compete for their focus. Someone with nothing but Christ doesn't require much sacrifice to follow Him.
