More people are working right now in the United States than at any other time in our history.
The same can be said year on year every single year (except 2020) due to population and economic growth.
What he doesn't say is that the divergence between the average wage and the cost of living has never been greater. So, while more people are available to work, they are earning less per hour in bread and bricks than they were 5, 10, 15, 20 (etc.) years ago.
