1, No I don't. I said plenty manage. Its true. The evidence is there, I think we can put that to bed now.
2. I know plenty of people who grew up in Sussex and Surrey and moved to lower cost locations for a better quality of life.
3. I don't deny we live in a world where some people earn more than others because they have higher value skills and fewer people with those to skills to compete with. I argue that applying additional taxes to wealthier people, to subsidise those who have less for the purpose balancing wealth inequality is a bad idea. A person living in the SE, who fits in to the top 10% of earners is not a wealthy person.
There is no incentive to strive to do better and there is less incentive for those doing better to do so. As I have repeatedly said, the solution is to invest in the skills of those near the bottom so that at least some of them can push themselves up and not only make a greater contribution to tax, but also enjoy a better life.
