Earlier quoted context omitted.
If I put in my time, if I learn valuable skills, if I make smart choices, if I choose to do something complex over something menial, then I would want to see myself doing better than people who did not choose to do those things, no matter how nice and kind they may be. Anything else, would be unfair and make me question the point of my efforts.
This assumes that poor people don't put in time, have valuable skills, make smart choices, or do complex work. It also assumes that they had the choices better than the position they have. There's also another assumption that the protections social safety nets completely eliminate incentive to put in effort. GP didn't say they moved to a nonexistant land where everyone is paid the exact same.
As 'unfair' as we want to believe, over and over, I've seen hardworkers prevail.
