Not to be pedantic, but isn’t the billionaire’s class wealth mostly derived from their ownership of an asset class that does draw from everyone, stocks?
Stock prices dont go up in a vaccuum. Most first gen billionaires got there by owning founders shares that were worth near nothing when they got them and billions eventually as their business made more revenue as a result of their stewardship. Said company iant drawing from every(ne in a vaccuum either. Thry make the money as the best option in a sea of options usually. There are market power issues in some instances but tjat isnt solved by rediatribution, its solved by breaking up the market power holders like weused to pre rhenquist supreme court
