Capitalism keeps funneling money towards the top, and the top gets smaller and more wealth-dense over time. Developed countries are doing this faster, because thats what their economies have been built around. But we are unironically reaching the point where the wealth accumulation by the billionaires represents an existential threat to the entire rest of the economy: you can't have a viable economy selling goods and services if there is no one left who can afford to buy them.
This economic restriction encourages people not only to spend less, but to do less. They have to devote more of their time just to making enough money to break even, which means no leisure time to build communities or find romantic partners. Our need to work as much as possible just to survive in the moment kills the soul of the nation on a communal level, and creates a population crash in the long term. The rich think they can fix the damage by importing more, cheaper labor from overseas but that only fixes the problem so far as their bottom line is concerned, not in any of the other ways that the system has become unsustainable. They think this will save them and let them continue business as usual, but it at best buys them time and honestly not a lot of it.
