Consider the fact that median real income tends to move up [1]. This is the metric that matters. It's the 50th percentile person, so mega rich outliers are ignored. And it weighs incomes against the CPI, which incorporates the price of medicine, construction, education, as well as consumer electronics, food, and pretty much everything people spend money on in realistic proportions. That's objective evidence that people actually get richer, even though the price of labor does tend to go up across the board, relative to goods.
