Wage growth in the US has been most pronounced in the lower end of the market. Growth-oriented businesses like tech are a lot more sensitive to interest rate spikes, since their entire model is to borrow a ton of money to pay highly skilled workers a lot to "disrupt" an industry and achieve very rapid growth.
That isn't necessarily contradictory with still struggling, since inflation exists. If you suddenly make 10% more money but everything costs 10% more as well, you are objectively making record wages, even though your buying power remains the same. Per that report, inflation-adjusted wages have actually grown on the lower end of the job market, so the average low-wage worker's buying power has actually increased, but general statistics don't always translate over to real-life experience super cleanly, and of course, a slight improvement from a bad financial situation doesn't suddenly put you in a good situation.
