Well, let’s put it this way ... planes won’t fly, bridges won’t hold vehicles crossing it and buildings won’t stay up ... if someone doesn’t know their stuff.
Maybe you can even up the job market for flipping burgers, but if you want your planes to keep flying ... that won’t work ... :-) ...
I am not so sure that all of them want everything to work. I have had people tell me directly, that they didn't really care how bad things got in America, as long as white people got hurt by it.
