I tire of this argument. They do. They pay taxes according to the laws of the land.
Are they being fiscally responsible by paying less to the tax experts than they'd pay in taxes? I don't know, but I'd suspect either those experts will always continue to justify their existence (e.g. "Yes, Mr. CEO, we've saved you oodles of money") or corporate boards and executives just prefer not to think about taxes and accounting and such and just keep some accountants and lawyers around anyway.
