I googled something like net worth of US billionaires and that was what came out on top. I was looking for the the $6.72T number, not the count of the billionaires, that count varies everyday be cause many up them are right at the $1B line. A strong up/down day in the market can change the number by 30.
My point is that even if you took every penny the billionaires have and passed it out to the general population you are only going to get a one time check for $17.920. And if they have to pay taxes first that one check will be closer to $14,000. Even though billionaires are extremely rich they are still nothing much when compared to the size of the overall US economy. The pandemic stimmie checks were of similar size and they weren't life changing.
People compare themselves one to one with a billionaire and feel very poor. But look at it collectively, if you confiscated everything the billionaires have they could only pay off the US deficit for about 18 months before they collectively went broke. And then we'd still have a giant deficit without anyone to tax. It's just a fantasy to think that taxing the billionaires can close the deficit or provide free healthcare for all. Use you brain and a calculator, it can't possibly work. Sure, make them pay more in taxes, but it isn't going to dramatically change things.
