Where are the factories shut down by higher taxes and many govt. regulations in all that ?

And the ones prevented from opening for similar reasons ?

I suspect very few industries would simply shut a factory down due to costs, regulations, etc.

What usually happens is that a factory reaches the end of its useful life or needs to go through a major upgrade in order to support the production of new products, and the company simply decides that they're better off building a new one overseas than replacing or upgrading the one here.
