I'll get modded into the ground, but whatever.
To teach my early teen kids about money, I offered them $20 apiece for each example they could list of how our "rich" neighbor could do something with his money that doesn't benefit me ( besides piling up his cash and burning it to death )
My son went first... "he could buy a million dollar car". (note: he actually drives a 2+ million dollar Veyron, but whatever)
Reply: "Nice try... But I'm a car salesman / builder / mechanic / own stock in GEICO insurance / sell gasoline & car parts / etc... He helped me even if he didn't intend to."
Daughter: "He could put it all in a bank account."
Reply : "Smart girl, but I'm a banker, that guy was super helpful opening up that account, since we need reserve deposits... if he had picked a stock market account that would also be great, my company sells stock to investors so we can expand and build more widgets, and we issue bonds for the same reason..."
In fact, I made it "easier" for the kids... assume that guy is a hateful jerk... now just list what he could do with his money to prevent anyone else from benefitting. What move can he make with his earnings that would benefit no one but himself ?
Anybody here want to guess how much I paid out? right... and thankfully my kids have not learned jealousy of other people's legal gains.
The end of the lesson was this:
The origin of "greed" is rooted in the concept of lusting for what you haven't earned. In context, it's similar to 'coveting'.
It's not evil to want to earn more by serving as many people as you can honestly.
And while we reserve the right to snicker at people who buy solid gold cell phone cases, we don't fall into the trap of greedily wanting to decide if they deserve it (after all, someone willingly traded it for their services) or if they are using their own money as we would. If they're bad stewards, they won't have it long, and in the meantime they can't help but serve others with that money, no matter what they do with it.
(That Veyron driving neighbor sells rap music, a lot of rap music I suppose... but it's a legal living)
