The Federal Reserve tracks wealth by households. 132 million households in the US. The bottom 50% wealth percentile ("lower class") in the USA is 66 million households. The upper 50%-80% ("middle class") is 64 million households. Of all stock ($55.4T), the lower class owns 0.01%, and the middle class owns 11%. The next time a politician says the stock market is at an all time high, remember how much that helps 80% of Americans. https://www.federalreserve.gov/releases/z1/dataviz/dfa/compare/chart/
