Exactly I think the UK government has not examined correctly the indirect taxes the wealthy generate in the UK. Each time they buy a high end property in generate a large amount of stamp duty and same with luxury goods, cars, art and services. They contribute to the many high end boutique businesses and restaurants etc in London that may not do so well if the wealthy disappear overnight. I think the government only looked at direct taxes these non-doms pay which does not give the full picture. Only time will tell indeed.
