In France, you cannot talk or say anything bad or dissident against Muslims and Islam or you'll get mugged, attacked, harassed or beheaded in the name of prophet Mohammad. In the UK, you cannot say that Muslims are the main problem behind the myriad of sexual assaults and crimes in the country or you'll be branded as a racist bigot and the police will put you to the slammer. In the USA, say anything that shows pride of being white and an American makes you a fascist. In Germany, anything that's right-wing in opinion is illegal and can get you to jail. In Sweden, talk about how the Muslims have destroyed your country inside and outside and your fate is worse than those who raped or murdered.
Have you Westerners lost your will to fight to preserve yourselves? Are really this desentized to the point that you're more worried about what the media will have to say against you if you stand up for yourself and your right to exist? Maybe it's cowardice.
I'd say it happened even earlier than that, when we moved away from the idea of the family farm and self-sufficiency toward living in the city and working in the factory. In my family I think my great-grandparents were the last generation who could truly have been said to be self-sufficient; after that everyone in my family has worked for someone.
Perhaps those days aren't coming back, but I still think something like a family business or a communal trust fund that each family member contributes to could probably help at least slow the treadmill down if not stop it entirely after a couple generations. Unfortunately that probably requires a level of financial sophistication that most people don't have, and the people most likely to benefit from such a system are the least likely to have the knowledge to construct it.
"Buy land, grow your own crops, raise your own livestock, pass it on to your kids to do the same" is certainly a simpler solution if not an easier one.
That doesn't work as well because of economies of scale. It's more efficient to centralize creating things that everybody uses. Not that it's better culturally, that's just how things work mathematically. You save time, effort, and resources by specializing and distributing.
I do wish that we would move more towards quality rather than quantity, but that is easier said than done.
The price of specialization is dependency on others, which requires a certain amount of trust in the people one is depending on. And typically, centralization results in more single point failures, and increased efficiency results in less margin for error.
It's a clock that probably can't be turned back, which is why a literal "family farm" probably is a non-starter. But when they went away we also lost an important family-level safety net that never was replaced with anything.
