> wages have remained stagnant for four decades…It's also a fact that the wealth gap is growing between rich and poor

First is sort of correct for a very specific slice of America, those just above the welfare cut off. (For whom real wages have been flat to negative, assuming we scale up housing preferences and add in costs that didn’t make sense before, e.g. internet and cell-phone bills.) The second—about rising inequality—is true throughout.

Neither advances your argument, however—one can better off while others are much better off, and most in a population can be better off while some are worse off. (Observe the median Millenial and the statistics stand. Millenials are rich, in part because we’re going to stick Gen Alpha with the bill.)
