If we assume the wealthy own the stock market, it’s $52 trillion - enough to pay off the debt and leave $16 trillion left over - which would cover about ten years (assuming the debt service has been removed by the payoff).
Whether nationalizing the entire US market would be worth it is left to the reader.
My grandpa went to prison (in Romania) in the 1950-es for being part of bourgeoise class because he fixed and ran a broken mill. He was a war refugee (from Romania to Romania) without any money, land or any other resources, but in Communist Romania running a mill would tag you as "super rich". I guess this is what you wanted to say there, correct?
I consider myself reasonably well-off but am unlikely to become even a millionaire in my life (inflation-adjusted). I’d say millionaire = rich, 10-20 million or more = super rich. See also https://en.wikipedia.org/wiki/High-net-worth_individual.
Not saying that the math would work out without problems then.
