From the moment it is built – and even before then, in some cases – infrastructure starts “crumbling”. As Paul Simon and many others have put it, “everything put together sooner or later falls apart”. So “crumbling infrastructure” is just part of life everywhere that infrastructure exists. It ain’ no thang.
Like others, I also wonder what you mean by “societal agencies”. Families? They generally seem pretty strong, as a rule, when they’re not too badly tampered with or engineered against purpose. (Maybe more on that later.) Corporations? You probably don’t mean them, do you? They’re simply thriving – and you can’t argue that they’re not societal agencies, either. Whatever you may think of corporations, they are “agencies” built by people in a very real “social” sense. So they sure aren’t “collapsing”.
I don’t suppose that you meant armies and navies, so I won’t assume that’s what you mean..
Did you mean, perhaps “some government agencies”, such as schools, or government programs such as the various forms of welfare that governments administer, including Social Security? I would 100% agree with you that those are collapsing, primarily due to the false premises that drive them and the lies that sustain them. Those human systems and drives don’t seem in danger of extinction: we’ve been educating succeeding generations since time immemorial, and “welfare” is practiced in various forms all over the world, usually better without government direction than with.
