I think one of the overlooked pieces of the email is on the second page. I read it yesterday so my memory isn't super fresh. But he essentially says that:
* they've been hiring people at $18-20/hr
* the government pandemic aid/unemployment is dropping off and therefore they are no longer "competing with the government"
I think a lot of the "progress" with increasing wages was artificially inflated by government overspending of unemployment and COVID benefits. The people out there looking for jobs were in a sellers market. They could get a better rate because people were staying at home because "they could make more on unemployment". Now we're moving back to a buyer's market as that runs out and people are forced to re-enter the workforce.
While I think we can agree what he is saying here is cold, he has an interesting point. Ultimately the government is responsible for this and it will be interesting to see how it impacts wages and the mid-terms given what inflation is doing.
Personally, it seems like we are in for a "correction" in the labor market where we will see wages go down since more people _need_ jobs and aren't relying on government handouts. But I think he's mainly pointing out that the wages were artificially high and are going to lower back down. Perhaps to $12-15 an hour? Who knows.
