I've always saved very aggressively, even when I didn't have any money. When I first moved out, I ate nothing but rice, lentils, eggs, and lard for several months to save a slush fund. Even today, I make ~15-20k USD below median income for my city, and I've managed to save just shy of 10k in the past year and a half.
Obviously the ongoing coat of living crisis is a big deal that needs to be addressed, but we also need to acknowledge that saving your money is unpleasant, and a significant number of people aren't willing to do what's necessary in order to build financial security.
My friends (I don't get out much, I only have a couple) all have significantly better income/expense ratios than I do, and have exactly nothing saved. Honestly I don't think that would change if you gave them all an extra $20k/year, because they will find a way to rationalize something into being a necessity.
