True, but that's kind of comparing apples to oranges. It's not every day where people do capital intensive investments like those involved in factories, and they usually only do so when they're fairly certain they'll get a return. That contrasts with funding SV startups, which is probably comparable to throwing darts semi-blindfolded and hoping something sticks. Sometimes it does; it usually doesn't. Also, the factories in the midwest were doing fine until they didn't; but nothing lasts forever. The factories in Shenzhen will similarly go under sooner or later. 3d printing, for instance, might bring some manufacturing jobs back to the US and Europe and put Chinese factories under pressure.
