And who gets all the money in the US?

The Federal Bank of St. Louis publishes various economic data. Some of them are very interesting not from the point of view of economics, but rather social justice. One of the most important social parameters is the share of labor income in GDP (labor + capital). The golden years of the USA, the 1950s-1970s, can be described as "labor gets more than capital", as can be seen from the graph of the share of labor in GDP. The share is slightly more than 50%. Then comes the time of losses. In the 2010s, the share already falls to 42 (!!!)%, that is, by 9% compared to the 1950s. About the same level in the 2020s. Since the overall gap between the share of labor and the rest is a double fall, labor has lost 18% relative to all other income recipients. Where does labor's money go?
