Ethics is relative. Truth is relative. Honesty is all relative.
Ask Bush... it depends, it depends on what you can get away with.
Here is an article how IBM is eluding that it should not have a corporate office, that it should make even it's corporate head quarters in the US, a satellite office, remove the concept of head quarters (as if you will pay less taxes, then). In other words, as a true capitalist, as a PNAC republican, businesses (IBM) have the right to evade taxes, this is what IBM is eluding to.

So then, a US citizen will follow suit. US citizens will ride the globalization wave and "decentralize", paying taxes only to those that she is obligated to. Obligation is to those governments that offer incentives.
Mikhail Khodorkovsky fvcked the Russian people up the ass by $28 billion, evading taxes, the US government called that "democracy". Tyco does it, and Dennis Kozlowski gets decades in jail.
The new message from the US gov is that you must evade taxes, except for the US tax machine. But the new order behind all this is a message that corruption is "good". Because when Bush lies about wmd or 9/11, that his lies are good. That corruption and message is ordering expatriates to hide their money, launder money as much as possible, and dilute any tax obligations using "transfer pricing".
When peak oil bites harder into the economy it will hammer the dollar. Expatriates will run, and hide their assets. They are being true capitalists, and chances are they will hide their money nearest the bright spots of the global economy, nearest energy.
IBM is running away from it's obligations. Everyone else is going to do the same.
