That looks like tax rate which is much different than tax burden.

Sorry I missed your post. You are correct with a qualifier for empirical evidence: US law requires US expatriates to pay the positive difference between what your US taxes would have been and what your foreign taxes are. I.e. if I would have to pay $10 in the US and have paid $8 in London, then I owe the IRS $2. There was a time when almost no-one had to pay into that scheme. Now, most people do as the US taxes have caught up with and in some cases surpassed rates in European countries.
