What are not facts?

Stanron -

"The non-domicile regime is credited with encouraging many wealthy foreign nationals to base themselves in the UK" Is speculation, Credited by who?

"a system which encourages people to leave the UK after a few years means that many will simply choose not to come in the first place." Is speculation. How many? Facts and figures please.


"Non-dom families will often make significant investments in businesses" Is speculation. Note the word 'often'. How often? How much?

Of course the rich spend and pay tax but once you base those facts on speculative assumptions they become invalid.
