To examine the credibility of such claims based on employment we have collected information about the average hourly earnings since 2007 as well as the corresponding consumer price index . This information was obtained from the Federal Reserve Bank (https://fred.stlouisfed.org):
US employees realized from 2007 through 2019 average gains of only 0.39%/year. From that we need to subtract other charges such as Social Security taxes and State & Local taxes.
Wage earners show only very small yearly gains as compared with the 7.8%/year realized by an investor in the stock market.
The difference between a wage earner’s annual 0.39% increase vs. the investor’s 7.8% annual gains arise between gains reaped from current incomes and gains realized from investments that deliver compounded returns.
