Actually the solution was already tried and tested by American cities. It's called diversifying the economic base. Instead of relying on 1 mammoth company, try to develop and sustain multiple smaller ones. All American cities that recovered from the '70s-'80s downturn, and even from the 2008 crisis were the ones with a higher number of smaller employers, startups, etc. The ones that diversified. Because they are more resilient to one company's failure.
