I am bugged more by local environmental impacts.
Around the time that manufacturing started moving to China en masse in the 1990s I started to hear about trichloroethylene contamination at manufacturing sites in the U.S. Look up "trichloroethylene united states" in Google and you'll probably get results about how our marines were exposed at Camp Jejune and are now eligible for V.A. benefits. A search for "trichloroethylene china" might turn up a picture of a truck full of barrels from a company that wants to send you those barrels.
That stuff is all over Silicon Valley. Santa Clara County actually has one of the most if not the most EPA superfund sites. It's the leftover legacy of chip manufacturing. When you rent in the Bay Area, the landlord does not have to disclose TCE contamination to you. TCE can cause birth defects and low birth weight in weeks if breathed in by pregnant women. If you're renting in the Bay Area, Google the address and make sure the property is not over a TCE contamination area.
