"When you say "less fortunate", or otherwise claim that fortune is the reason someone has more, then YOU are saying they didn't earn it."

No I don't. That is a false conclusion you drew so it would fit your argument. I largely don't care how worthy somebody is of having wealth. All I care is that he, being wealthier then others for whatever reason , would help others improve their well-being.

If he isn't going to share his wealth with the rest of society, what need does the society have for him? Why shouldn't the society simply expropriate everything? If he isn't serving his function in the society, if he doesn't want to be a part of it, if he doesn't want to share, if he os not part of the team WHY should the society provide him with security and protection???

Of you are not part of the group, you are an outsider, and if you are an outsider, what moral reason dors the society have not to simply take everything away from you???
