>> How would the world be a better place if we stripped executives of their wealth?
>Would a redistribution of that wealth imply better living standards for everyone?
Basically no. This is the misconception about wealth inequality in general.
Living standards are more about goods and services produced, not numbers in a bank account. The wealthy consume more, but not proportional to their wealth. most of their wealth isn't used for consumption at all.
Elon Musk must doesn't eat 100 cattle a day, have 1,000 personal doctors, or live in 1 million different houses.
If you took all of Elon's wealth, sold it off and redistributed it (assuming this is even possible), you would just see more expensive burgers, more expensive doctors, and higher cost of rent.
This is because Elon isn't using up all the resources. He just has a higher number in a computer somewhere.
