It’s not real consumer/producer, real compensation is inflation-adjusted
Well, the mean compensation is always going to be higher than the median, right? The graph was originally posted to show that wages grow slower than the productivity. Both graphs are for the workers, but a lot of the difference is mean vs median. There are also other factors.
For example, total compensation grew faster than wages because company health plans just cost companies more these days. Health care prices grew faster than inflation, so clearly companies had to pay more for them.
In recent years the real (inflation-adjusted) wage growth has been solid
The price of groceries in hours worked had been mostly dropping
You can design algorithms specifically to mess up parallelism by branching a lot. For example, if you want your password hashes to be GPU-resistant.
