> The only way a wealth imbalance can occur is that someone sits on wealth and that it continues to compound. The top 1% have wealth greater than the bottom 95% of the population combined. I don't see why its more moral for someone to sit on investments than to have the money distributed to others to spend.

The critical insight is that this doesn't actually work. When we say Jeff Bezos is worth $200B, we don't mean that he has $200B of money that's locked up in a vault when it could be redistributed. We mean that there are a variety of productive businesses in the world - for Bezos, mostly Amazon - which he holds ownership claims to. The vast majority of wealth in the modern US isn't money, and can only be converted to money by finding people with lots of money and selling them the right to sit on the investments instead.
