The Telegraph had an article on which of the US presidential candidates would be good for the UK. They said of Obama:

Clinton's main opponent, Barack Obama, has many similar health care proposals but one area in which they differ is in his plans to abolish tax breaks for the wealthy and to prevent the use of tax havens. This would have an obvious affect one of Britain's growing industries - the alternative investment sector, with private equity and hedge fund managers hit the hardest.

Due to the cross-border nature of many working within the industry, reining in taxes on a sector that has traditionally benefited from an ability to manipulate the amount of tax paid would have an obvious impact.

I wonder if anyone on the Telegraph could say why the ability to manipulate tax paid is good for Britain?

I look forward to a reasoned answer.
