> I can't help but notice how weakened this entire process is as a result of revolving around money. In terms of manpower and expertise, none of these changes really need to happen, but since everyone is chasing a buck as a matter of survival, a bunch of stupid stuff occurs.
Resiliency against interruptions costs a lot of money: warehouses to store parts, logistics to rotate these parts, paying suppliers for these parts earlier than the parts are needed, waiting until you have enough cash to buy stuff outright...
The core point is: governments, businesses and individuals have historically always had these costs - but at least the Western world has been enjoying a couple decades without major interruptions like war on the home territory, oil crises or the looming threat of the Cold War getting hot (and causing interruptions as a result), which means everyone got incredibly complacent. After all, when there are no interruptions to expect in the near term, why spend cash in the near term to guard against them?
And so, when Corona hit, everyone got hit.

The existing buildings may not go crumbling, but planned/under-construction buildings are getting put on hold when the banks' income stream vanishes and as a result of that, in turn, the workers can't work, ... <insert recursive ripple effects here>.
