Wages were mostly flat again last year, even as the stock market rose to record heights. This is kind of what we expect nowadays: The divide between Main Street and Wall Street has become a staple of stump speeches everywhere.
But it didn’t always used to be this way. In fact, for a long time market performance tracked fairly closely with wage increases. But that all changed around 1980, when stocks took off and compensation languished.
What happened? To answer this, we’ll need to start with the chart below. I’ve plotted the relationship between stock market performance and workers’ compensation over the past 60 years, since 1948. It’s a timeline, starting at 1948 in the lower left corner and ending in 2016 in the upper right, that snakes around depending on the change in pay and in the S&P 500 each year.
You can divide this timeline into two major periods. From 1948 to about 1980, stock gains were relatively modest while pay rose significantly. Over that period, average hourly compensation (including wages and benefits) in real terms rose close to 90 percent, from $12.37 an hour in 1948 to $23.32 an hour in 1980. In inflation-adjusted terms, the S&P 500 rose by about 145 percent during that time — more than wages but still at about the same order of magnitude.
Now, look at the period from 1980 to 2016. You can see that the line flattens out as wages stagnate while the stock market booms. Over that period, average real compensation rose 14 percent, to $26.61 an hour. The S&P, on the other hand, grew by 502 percent.
What we see, in sum, is that earnings and stock performance were closely correlated until about 1980. But around that time stocks began to peel away. Whatever coupling once existed between the market and wages appears to be gone or at least severely weakened.
“Stock market gains and near-stagnant pay for most workers have the same root cause: the policy-induced shift of economic leverage and bargaining power away from typical workers and towards corporate managers and owners of capital,” says Josh Bivens of the Economic Policy Institute, a progressive think tank.
There’s a laundry list of reasons for this, and if you’ve been following the recent national debate over inequality, they’re probably familiar to you: low minimum wages, the decline of unions, globalization, shifts in tax policy.– Washington Post
