The people who made things work will die of old age or withdraw their support (on strike), LLM's will prevent new workers from developing the same expertise (since entry level positions will be removed).
Systems that have stood strong as oaks for centuries will suddenly fail, and with that collapse so too goes the food production.
Non-market socialist systems don't work, but you get those same systems during currency collapse (where ponzi outflows exceed inflows, or debt growth exceeds gdp).
No one knows a thing because socialism has done its dirty work, having captured academia over the past 50+ years, and indoctrinated the masses.
The benefits were front-loaded (as all ponzi's are), and it happened slow enough that no one noticed over multiple generations, and the generation that got the most benefit won't cede political power (they took power in the 1990s, and remain the majority today). They'll give it up only once its pried from the dead hands, which will come from natural aging.
Menticide from the Totalitarian state has a deleterious effect, making it harder for people to see the problems to take any action. Joost wrote extensively about this with regards to the Nazi's and Mao.
What we are seeing today is hubris and a natural consequence of ignoring lesson's learned.
