In my church, we periodically hear the Gospel account of Jesus telling the young man to sell all he has and give it to the poor, but I just go to a regular Catholic Church so what do I know?
It's easy to determine who really ascribes to the belief and those who do not.
It often suprises how many of my liberal Catholic friends get confused by this, but the Catholic faith actually has nothing against individuals amassing great wealth. As a matter of fact, the Church encourages individual achievement for God's glory, and this necessarily includes at professions that are rewarding. What the Church does require is that every individual give 10% annually to charity. The confusion comes from the parable where Jesus says it is more difficult for a camel to pass through the eye of a needle than for a rich man to get into Heaven. He was talking about the added temptations, not any prejudice God harbors against rich people. There are many good rich people.
