That might also play into it. 'Hard work' is only good if it's fruitful and fulfilling, if it actually produces things that will endure. These days it's defined by a slavish willingness and the number in your bank account. There's nothing to be proud of and almost nothing to actually show for it but damage to ones pride and dignity and degradation as a man.

There are a myriad of other factors stacked on top of all of the above.
Overpopulation also has a compounding effect on this behavior (for the K-selected human sub-species). It's not an especially well understood mechanism though.

The reality that most people never consider when looking at these emerging situations is that populations can grow and shrink naturally, sometimes dramatically. The only people this effects negatively, as long as you're able to resist the drug of mass immigration, are corporations and their bottom line. Letting a population shrink ends their infinite growth curve.

And yes, these entities are perfectly willing to sacrifice an entire nation, the entire demographic make up of a country, to marginally improve their bottom line. All in the name of 'GDP' which means literally fucking nothing to 99.99% of people.

Never mind plastics and estrogen mimicking chemical in everything.
