There are more 'things' as a function of decreased costs of production, including, get this, importing lots of cheap goods from overseas. 1950 to 2020 looks good on paper, until you realize that the bulk of the wage growth happened prior to 1990. Since 1990, the S&P 500 has gone up approximately 10x. Meanwhile, wages have approximately doubled. That means in the last 30 years, the wealth gap has increased. If you consider only minorities, the picture is even worse. It's almost like, US workers are losing their bargaining power for some reason. If you consider outsourcing, various trade agreements, and white collar immigration, those are all net-negative on US labor. Some demographics have been disproportionately impacted than others, just as predicted.
