Monetary theory is complex, and lots of stupid people want it to be simple.
“<Complex subject> is complex, and lots of stupid people want it to be simple” applies to far too many subjects, and politicians tend to use that to manipulate voters when those subjects are societal.










No, they are being deprived by the fact that billionaires are allowed to amass that amount of wealth without supporting society with it, i.e., taxes, labor laws that don’t allow the extraction of wealth from workers to the point that there is often an income disparity if 100000%, and comsumer laws that don’t allow vendors to charge exorbitant rates for basic necessities like food and housing and medicine. So someone can take trips to space and someone else can’t have food, in the more extreme examples.
You keep conflating artificial and unrealized value. Stocks have value, just like the cash in your wallet or the bits associated with your bank account. They aren’t physical things (even cash has no value based on its physical nature) but their value is real nonetheless. At least until society collapses and the only things that matter are the purely physical, anyways, at which point your cash will be just as worthless as stocks.
