It’s Boomer retirements, which they knew were coming for years and low-to-zero immigration. So many businesses have had to backfill, and it’s trickled down to no one having to work crappy $10/hr jobs with customers. So many other businesses relied on an underpaid person born in 1959 who hasn’t had a raise in 20 years because they were content, and now that person is gone and those businesses want someone with the same level of expertise and the same or lower wages.
