"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.

So is the suggestion of less light and more isolation in Sweden. One of the darkest and most lonely countries in the world. There is already no requirement for windows in bathrooms and kitchens, as you can't regularly open windows in winter anyway.
