This really is quite lovely:
I will state the obvious fact that this should not give rise to a right to preferential tax treatment – but it does. Discrimination on the basis of national origin in this way is wrong. So why does the government do it?
So, today, discrimination in taxation on the basis of national origin is wrong and naughty.
Ritchie in a report for the TUC some time ago:
First we propose that everyone who has a UK passport should be tax resident in the UK, automatically, wherever they live in the world. That means they would always have liability to pay tax in the UK on their worldwide income, gains and wealth, just as all US citizens do in the USA.
So discrimination in taxation on the basis of national origin is just fine and dandy apparently.
