Does the median income track the boss’s newly increased wages, then?

It’s something I’ve been thinking about for awhile now. That labor wages are stagnating but because “management” level, and higher, salaries are increasing with productivity, these Median Real Wage statistics are skewed, showing the increase.

I would have no way of separating out labor wages from the management level wages though, was just curious how it’s calculated.

This could just be due to usage change over time, similar to how “literally” can mean the same thing as “figuratively” now a days. But I’m not an etymologist.
