&gt;If the Facebook UK staff relocated to Dublin then the loss to the UK economy would be exponentially worse.<p>Can anyone say that for certain?<p>How do you know, for example, that the same staff they&#x27;d employ wouldn&#x27;t end up working for a company that <i>does</i> pay a large amount of corporation tax, leaving the UK&#x27;s tax coffers <i>substantially better off</i> than they&#x27;d be otherwise?
