Real people don't care about "real income". They care about if they can get and retain a decent home, job and life. How much debt they are in, that their education is enough, how their social life is, if they can have kids and how they think about their future.
"Real income" is measured against the consumer price index (CPI). CPI is used to gauge inflation, "are people paying more for groceries this year than last?", not living standard. Most of the important questions like "how many years of education do you need for a good job?" or "how many average salaries do you need for a good home?" are all massively worse. So are many metrics of despair.
What real income really shows is that more money now gives you less. That what buys you a loaf of bread doesn't buy you a good life anymore. Because median income might be keeping up with inflation, but not with anything else.
