Actually, I'm interested that many of the people in this House who believe that taxes are actually effective in stimulating the economy are the same MPs who would argue that imposing a tax on capital income is going to constrain capital growth. That's what they want it to do. That's what they want it to do, to dampen house price inflation. So if higher taxes on capital growth will blunt the effect of them, surely they've got to be consistent and acknowledge that higher taxes on income are going to have exactly the same effect.
