Polanski suggested this morning that a wealth tax is the right thing to do, even if it raises no revenue, and encourages some very wealthy people to move abroad. He justifies this because it would make society less unequal, which is, he suggests, a positive end in itself.
I wondered what other people thought about this? I see little to be gained by instituting a tax with no fiscal benefit, and no community benefit in reducing spend in our economy be removing some of the biggest spenders (if they move abroad). What do you think?
