The United Kingdom is about to discover the part of the Laffer Curve where the billionaire taxpayers simply get on a plane and go somewhere else.

His Majesty's Revenue and Customs has now assigned a dedicated "compliance manager" to every billionaire it has identified with a UK tax footprint, dramatically expanding the government's oversight of the country's richest people, according to a new report from Bloomberg this week.

HMRC is using its own records, public information and data shared by foreign governments to identify billionaires with UK tax exposure and map their connections to businesses, trusts and other entities. "The UK tax authority has assigned a personal compliance manager to every billionaire within its reach as it seeks to get a better grip on the super-rich's tax liabilities," the report says.

HMRC says the goal is straightforward, making sure wealthy taxpayers pay what they legally owe, and the government confirmed this month that every billionaire with a UK tax footprint was allocated a Customer Compliance Manager over the summer.

But consider the message Britain is sending: become extraordinarily successful, build companies, accumulate enough capital and pay enough taxes, and eventually the government assigns an individual bureaucrat to keep tabs on you.

At some point, you have to wonder whether the people designing these policies understand that billionaires are among the most geographically mobile people on Earth. They literally are the most mobile people on the planet. They don't have to stay.

And they won't. They can live in Dubai. They can establish themselves in Monaco. They can move to Malta or Switzerland or any number of jurisdictions competing aggressively for wealthy residents, investors and entrepreneurs. Their businesses, capital and families are often international already. Moving is inconvenient, but for someone worth several billion dollars it is hardly an insurmountable obstacle.
