Edit:I did say _anyone_ in the past 20 years so that is some unfortunate hyperbole on my part
This doesn't make a lot of conceptual sense. If 100,000 people move into a town of formerly-3000, they will severely outnumber the open job slots from before they moved in, but that doesn't mean no work is available for any of them. Most of them will find work just as most people everywhere find work.
Work is available to anyone who can do something productive.
