It’s no surprise unemployment has been low since then. Coincidence? You can decide.
I’m more curious what the ratio is between the median monthly “necessary” expenditure is, adjusted for locale to median salary. My hypothesis is that it’s drastically going up - that is, the median person working the median job requires an increasing high percentage of their salary to afford the “median lifestyle”. And in some cases this could be over 100%, meaning the median lifestyle is sustainable only through debt or other compromises like roommates, below median quality of life etc.
People have tried to get around this with brutal commutes, but we are seeing the limits of that as living far away no longer yields much savings but still results in a long commute.
