Yes, I am aware of the protectionist myth that real wages are constantly falling. It’s like their belief that the Earth is flat.
You have to look at earnings by income group. Those grand total, nationwide average per capita figures some love so much are meaningless. Few still deny that the earnings at the lower pay scales in the US have been stagnant and declining. People in the lower income groups are the ones who more and more qualify for various government low wage subsidies, which are becoming a much greater part of our federal and state budgets.
