wtfhappenedin1971 has approximately 17,000 graphs showing wage suppression. I will 100% eat shit on this if you can show real evidence that QE (printing money, whatever) is the main cause of wage suppression.
It is exactly what has happened over the past 4 years, spread out over 50 more gradually. Since January 2020 CPI is up 23%. If you received a 5% raise each year the past 4 years, you'd have a real lower wage today than you did 4 years ago. People are not inclined to complain about "gifts" of raises, yet those raises quantifiably do not keep pace with inflation. The problem is that this is invisible for the vast majority of people. How can I be earning less even though I'm now making $xxxx more than last year? Workers' wages stagnate while companies are able to reap the benefits of reduced labor costs.
You can also see this with things like the minimum wage. In 1968 the federal minimum wage was $1.60. Inflation adjusted that's $14.42. Places like California/Washington think they're being progressive with their minimum wage ideas, but it's simply trying to take us back to before 1971, except with all of the problems that the 50 years in between have caused such that the quality of life that money will provids will likely remain dramatically lower than it would have provided in 1971.
