I hear this suggested a lot on mumsnet and I really disagree with it. High earners are paying a huge contribution in tax already - thousands and sometimes 10s of thousands more than a lot of people who are clamouring for them to be taxed even more! Why should they be punished for having a highly paid job? How would you like handing nearly half your income over to the government? I think we should be thankful that we do have high earners who are already making a significant contribution. We would be a lot worse off if we drove them away with higher taxes!
