It's very relevant to the question of whether real wages actually did go down. If people live better than they did in 1950, and they do it on 2013 wages, then real wages did not actually go down.
There must instead be some mistake in the way real wages are calculated. (Hint: there are many, mostly in the computation of CPI.)
