I once oversaw moving a firms's HQ and IT functions from Silicon Valley to San Antonio, TX because of the "math" some white collar genius put together like this Forbes nonsense. Sure, the "average" wage was one-half of what it was in Palo Alto, but because of the "quality" of local talent, we ended up hiring THREE TIMES as many staff to do the same amount of work. (For the math-challenged, that meant productivity sucked by 50%.) This wasn't just a drain on company resources, but on the few people who DID know their chops and had to hoist it in for the dullards. Those that made the move and saw the disaster had to in turn move completely out of the area to restore sanity to their careers. And the "icing on the cake" is that San Antonio is the only place I've stood hip deep in mud and had sand blow in my face. No thanky-thanky.
