There is a technical term lawyers like to use for behavior like this: "Fiduciary responsibility to shareholders to minimize tax liabilities within the law." (We're a little more long-winded than economists.)
I think it can do it a little better.
what does "better" mean (honestly)? these are income taxes, not a CSR issue.
My better was in reference to the hyperbole, not that I can avoid paying taxes better than Apple. I know full well that they are not tax evaders, but are in fact employing a legal tax avoidance scheme.
But unless you're afraid of public backlash, and you should be, own up to it. Don't hide behind a bunch of hyerbole. Tim Cook said "We don't hide a bunch of money away on some Caribbean Island to avoid taxes." Technically true, but that's because the island Cook chose simply doesn't happen to be in the Caribbean - it's in the Atlantic.
Apple keeps 65% of it's world wide income in Ireland, which houses only 4% of Apple's income and about 1% of it's retail sales, including revenue from patents that were researched and developed in America because they transferred ownership of them to the Irish subsidiary.
