Huh? Since when? 1980? Almost all actual chip making plants have long, long left California. CA environmental regulations are no joke, and chip making plants use lots of very toxic chemicals that run afoul of the CA EPA.
I was involved with setting up and running a chip plant in San Jose. Yes, it's tough. But the chemicals are toxic no matter where they are, and have to be handled the same everywhere (at least in the US...).
