I think we are all beginning to understand what the ancient Romans experienced when their world fell apart as their ruling class failed and the barbarian hordes rushed in to dim the light of the Western civilization for at least 500 years.
Yup. There are some letters from a Gallo-Roman nobleman from the middle of the 6th century that survive where he complains he can’t get the baths at his villa fixed. That’s because with the collapse of urban civilization you lose the technicians who know how to keep the infrastructure running, like plumbers and masons. He also complains he can’t travel without a retinue of bodyguards because of bandits. Just like many major American cities.
