That's a fair point, but it remains to be seen what the frictions are. I doubt that the domestic software industry has had my welfare particularly in mind all these years up till now, and yet they're all still here, paying what everyone wants us to think is our exorbitant American salaries. What is the point at which these giants collectively tell us to fuck ourselves and run off to the Chinese nirvana you describe? Is it just north of where we are already, so if we don't get some immigration relief immediately we're all doomed? Maybe. Or maybe the whole process isn't as clean as you're implying that it is. I do know that for as long as I've been paying attention a standard Republican refrain has been that if we don't lower our taxes to zero then all industries, in their game-theoretic wisdom, will evaporate from our lands. And yet businesses keep failing to migrate en masse to whichever Dakota has no taxes, and Minnesotan industry draws another day's breath. To reiterate, I'm not saying you're wrong; but the causal chain is considerably more entropic than you or pg are letting on.
