I think everything that needs to be said has already been said about the OP's question. I just wanted to comment concerning Starbucks and tax.
We shouldn't be celebrating crony capitalism. Regulations and taxes that are selectively enforced against smaller competitors to the mega-corps are not better than regulations and taxes that apply to everyone.
Looking at it from their point of view, when the government slaps them with a 60% tax rate can you really blame them for trying to worm their way out of it? Taxes are at the point where they're just ridiculous, and everyone tries to cheat on them as a result.
