> A wealth tax than caps one's inflow to something like a million a year makes a lot of sense. To all the billionaire sympathizers

Perhaps the "billionaire sympathizers" are people who can manage to see that the bar for what is considered an unacceptable amount of wealth will keep being revised lower and lower until it affects them. Here you are already proposing that a person shouldn't be allowed to earn more than a total of a million dollars in income every year, which caps one's lifetime wealth accumulation at $40-60M[0]. Which would make anyone able to achieve anywhere close to that sum as wealthy as today's wealthiest persons. After which the next person will suggest that such a thing shouldn't be allowed for the betterment of society.

0: assuming you can start earning that much starting at age 20 and you intend on retiring between 60 to 80, so obviously the range can go up or down a bit.
