I don't get it. Why does what they do have anything to do with what you or I do? Why does anyone begrudge someone else for being lucky, harder-working, in the right place at the right time, better looking, fitter, smarter, better at business, better at making connections, faster at learning, or anything else that helps them acquire more wealth? Was it at your expense? I've certainly been passed for hiring because someone found a better candidate. I've receive smaller raises than a co-worker probably because they did more impactful work. I'm sure I've missed opportunities due to office politics.
I guess this is where we should all whip out the "U mad bro?" meme.
