The very idea that you should be able to determine how much wealth another person earns and keeps is the real social cancer.
Greed is the love of money.
There is no sin in having, earning, and keeping your own wealth. God loves a cheerful giver, not one that is coerced.
True greed is the violation of the 10th commandment to not desire the possessions of others. Violation of this commandment is the basis of the leftists’ ideology.
