I'm not saying it has to be perfect.

I'm saying that this outcome will never exist because more has changed than just the plant closing. If we coupled "reopen the plant" with "the plant makes entirely new things" and "the plant trains local workers to take these jobs" and "the plant pays above local service/construction wages" and "the plant will be successful in geopolitical competition" and "the plant can do 10x the amount of business due to advances in automation to get to the same level of employment" and on and on.

We could solve _each_ of these problems, absolutely - but they are all interlocking parts of a wicked problem. Blowing up the economy and threatening a global recession won't actually solve any of these.
