That is not hourly earnings. Americans are working longer than they did in 1970.

On top of that even if we take your link at face value that's a 0.35% growth per year. The medieval warm period had faster wage growth.

Only because the inflation metrics don't include housing.

CPI-U is deceptive and misses the point entirely, cheap t-shirt and televisions don't matter when people can't afford healthcare or housing.

Honestly, even if that takes into account housing and everything, doesn't that seem... pathetic? All of the automation and technological advancement and productivity gains over the past 45 years, and average workers in the US see a measly 15% higher real wage over that timespan. Compared to the obscene (real) wealth increase by those at the top during the same span, this seems pathetic to me.
