As Curtis James Jackson III (better know by his stage name 50 cent) once said...
"Get rich or die tryin"
Just kidding
I couldn't have a conversation with you about this if I tried, my knowledge of economics is equal to that of a monkey's. I'm sure there are some issues when it comes to the different wealth tiers around the world. The way I see it money isn't everything, but it's nice to have. If you want to make a lot of money there are thousands of ways to do it, many of which just require a bit more work than your average middle class career.
I'm going out on a limb here but I don't think Iger was handed CEO on a silver platter. I'm sure he had to get the right education and work his way up the food chain, only to find he had to support the weight of one of the biggest companies in the world on his shoulders. Sure, many careers are much harder and don't have nearly as much compensation, but everyone knows how much big company CEOs can make so if you want to make that much then follow the path to become a CEO.
I'm not sure if that makes sense but that's just my point of view.
