I'm not the OP, and they may be overstating statistics (happy to be shown otherwise). At the same time, wage stagnation is no myth:
"From 1973 to 2013, hourly compensation of a typical (production/nonsupervisory) worker rose just 9 percent while productivity increased 74 percent. This breakdown of pay growth has been especially evident in the last decade, affecting both college- and non-college-educated workers as well as blue- and white-collar workers. This means that workers have been producing far more than they receive in their paychecks and benefit packages from their employers."[0]
"The minimum wage peaked in inflation-adjusted value in 1968, when it was equal to $10.15 in 2018 dollars. [...] As of 2018, the federal minimum wage was worth 28.6 percent less than in 1968" [1]
"While the cost of a four-year degree exploded to $104,480 [from $52,892 adjusted for inflation], real median wages only went from $54,042 to $59,039 between 1989 and 2016." [2]

"In U.S., wage growth is being wiped out entirely by inflation" [4]
