sadly, no.
I am old enough to remember the regimes of Prime Ministers Wilson and Heath.
Recall the Beatles’ song “Taxman”?
British entertainers and other wealthy were leaving the country in droves to avoid 90%+ tax rates.
Then came Mrs Thatcher.
But they did not have to renounce their citizenship. The USA is one of the few countries in the world that taxes you if you live and work outside the country.
It won't be
Democrats only fleeing the US and its Tax Regime under Obama (or Romney if he does not aggressively reverse the engines full steam with a cooperative Conservative Congress) and it will not be just the super rich, but I predict the upper middle class to the so called upper class. That's when the German shepherd dogs, barbed wire, spotlights and armed guards get set up at 100 yard intervals on our Southern Flank, finally,
ironically to keep Americans, i.e. tax donkeys, as in beast of burdens, with means from leaving, and of course the Socialist Border Guard Detachments will have orders to shoot on sight anyone fleeing, but welcoming with open arms anybody who appears to be poor, going the other direction INTO THE US (instant Entitled Democrat Voters for Life),
trying to get into the US and the never ending Big Brother gravy train. I don't see how they can keep the benefits up though if the job creators of this country start voting with their feet in massive numbers as I predict, starting with serious professions such as surgeons and nurses.
