Milwaukee in the 50s and 60s is an example of this. They built a lot of amenities and expanded infrastructure with public funds.
The growth stopped or reversed and there is no money to maintain the same level of services and amenities today. Thus underfunded parks, roads, pipes and museums. Aka, not a strong town but one struggling along.
"Women need to have more babies because our entire economic model is built on growth and doesn't function without it and one of the best ways to grow is increase the population so you increase the taxable base."
You can slice it up however you want. You can bitch and moan about feminism if you're a woman, you can bitch and moan about men's rights if you're a man, but the bottom line is we need a lot more people to pay for all the tab we've run up.
Are they intentionally not meant to last?
Also, with regards to the US interstate system - why is it designed in such a way that any maintenance required a dramatic decrease in travel throughput?
Could it be designed to be functional in ‘maintenance’ mode?
