As it's budget day here in London I will make a rare concession to things that are happening now, rather than the late thirteenth century. Philosopher Stephen Law, whose debate with William Lane Craig I discussed in a few posts last year, has an excellent and entertaining rant about taxation and the rich on his blog here. The comments section is especially funny. Law's premiss is that the Conservative government has a lot of rich mates and that their entire policy is designed to make them richer, and the poor poorer.
This is presumably why today's budget will include a rise in the 'personal allowance', namely the bit you substract from your taxable income, and which therefore isn't taxed at all. The rise will take some people out of the tax net entirely. And presumably why the London Times today has a headline saying 'Super rich to pay for Osborne's tax cuts'.
I could make a whole post and more about the logic of taxation, but not today. Perhaps later. (Actually our friend Anthony who occasionally posts here knows something about this, but he has been a bit quiet lately. Where are you, Anthony?)
