Short answer: The market in the long run is becoming more efficient.
Previously, a guy only needed to have a job and regular showers to get a girl, since jobs and showers were scarce. Similarly, a girl didn't have to restrain herself from a surplus of calories to get a guy, since they were scarce.
Both of these are no longer the case. The guy increasingly needs Game, which fewer are willing to learn. The girl increasingly needs to ignore ever more convenient and tasty calories, which fewer are willing to do.
The few that do are getting increasingly more attention from the opposite sex, while most are getting less, since most are unwilling to do the work.
The market is thus increasingly rewarding those who do the work, and punishing those who do not.
Let's switch examples.
In the past, folks could live at or near paycheck-to-paycheck, due to employment being stable. Why? With less technology, the market moved considerably slower, so skills were useful for longer periods.
Today, that is no longer the case. Thanks to the long-run unstoppable march of technology, markets move faster, skills become obsolete quicker, and employment becomes less stable, so living at or near paycheck-to-paycheck becomes ever more impossible.
The market is now increasingly rewarding those who can defer gratification, and punishing those who cannot, which is most folks.
And no, no amount of socialism will fix the above. Who do you think owns almost everything right now? Who do you think ran socialist countries in practice?
Same group of folks. The smart ones have, and always will, simply switch sides publicly, to stay in power privately.
As I've said before, stop waiting for something outside you to save you. Save yourself.
The market is increasingly rewarding only those who do, and punishing those who don't.
