I was thinking about the labor shortage this morning, and realized something: The workforce grows, historically, about 1-1.2 million people per year. The current workforce is down by two million from two years ago, which means that we have about 4.5 million fewer people in the workforce than we would expect to have at this point.
There are about 160 million people in the workforce. If you assume a 40-year career, that means you get about 4 million people retiring each year (maybe a bit less, due to do demographics), and 5 million people joining the workforce each year. As a thought experiment, let's assume that those 4.5 million "missing" workers are all people who were near retirement, and covid gave them a reason/opportunity to retire. That's about one extra year's worth of retirees. That would mean that over the next few years, we would expect to see a lot fewer people retire (because many from that cohort already pulled the plug), and after those few years, we'd expect to get back to the earlier trajectory.
A larger-and-earlier-than-expected cohort of retirees also has interesting implications for the stock market, as those folks transition from accumulating to spending.
