An argument can be made that poverty is negative reinforcement - the wages of sin, as it were. If there were no downside, no consequences to sloth, drug dependency, foolish living, then many more people would choose the easy or low path. I'm not saying that everyone who is poor deserves to be - probably not even the majority - but surely some are poor by their own choice. And that is one way poverty can be a human justice
How can we have so much and justly not share?
Personally? I don't know. But as a society? Who decides who has to give and how much? That's the problem. If it's not voluntary, it's tyranny. When you become enlightened, you give of yourself and your blessings. When you force others to give, at the point of a gun, you rob them, not only of their time and hard earned wealth, but also of their chance/decision to become enlightened for themselves.
There is a place for the Govt to help the poor, but IMO, the govt only steps in because we don't -- or not to the degree required.
Most people are selfish pigs. Churches are empty. Malls are packed. I don't know what to tell you, but more tyranny of the majority is not the answer.
