As others pointed out, there are an awful lot of people who live in places where $100-150k is not close to wealthy. A small number of large, expensive cities has a giant percentage of the population.
How is anyone surprised that when inflation stays up for a while, people find it hard to maintain their standard of living. When you compare the person making $150k to the person making $100k, it doesn’t mean that they’re pocketing $50k every year, it means that they’re likely renting a more expensive place or paying on a more expensive car. They’re likely both just living within their means and, of you make everything in life cost more, both are going to have a hard time paying their bills. It’s not until you get to people who are making more than they can spend that that changes.
