If money was originally distributed magically - by an amoral higher entity of some sort - would you be in favor of some democratically decided redistribution afterward to make it a little more fair? What if you had to decide the answer to that before you found out how much in lifetime earnings you'd be randomly assigned?

The unfortunate fact of our world is that, statistically, very few people escape their demographic and psychographic destiny. You can predict a 6 year old kids earnings as an adult fairly well from a mix of their birth geography, parents income, an iq test, and the marshmallow test. Some level of redistribution, that still rewards capitalist endeavors, makes sense in a society as unfair as ours.
