It's curious that the percentages used to defend not taxing the rich (whether they are UK citizens, or operating as "non-doms") tend to be what percentage of the tax burden they pay. But it's never what percentage of their income and capital gains they pay as tax.
I think the latter is a fairer representation, considering we have a progressive taxation system. Someone who is earning over £125k a year should be paying close to 45% of their income and capital gains.
The question is: are they? If not, why not?

Because they're non-domiciled and for several centuries the UK didn't tax foreign income of non domiciled residents. It's not a mystery, it was the law.
The non-dom's came to the UK because of this tax regime. The UK can either have the revenue they get from them, which is substantial. Or, it can remove the non-dom regime, hope they stay, but be prepared for total loss of their revenue if they leave.
There's no magical third choice where everyone in that non-dom category stays just cause and pays more money. So far it looks like UK tax revenues are set to diminish from this change.
