Whenever I point that inequality out to people of the third estate, more often than not I get the response that the rich just got their wealth from hard work and that I am a communist for suggesting that anything's wrong.
But a line needs to be drawn somewhere of how wealthy you can get before it’s “too much” and has a negative affect on society. And how we can distribute a portion of that excess wealth to the people who would get the most benefit from it.
I don’t think anyone’s going to be discouraged from putting in the work to becoming a billionaire just because their billions are taxed more than their first few million dollars. That money accumulation has diminishing returns on value to self & value to society.
