The key part there is that even people who should be financially stable are living at the limit of their means. As the cost of living continues to climb, most people are going to start finding themselves in financial trouble regardless of their income.

Once they're no longer able to pay they have to sell their house, but if nobody can afford to buy it then they're fucked. And that's what leads to crises like in 2008.
