All the things we could have done with a capital gains tax

I'm interviewed in this Spinoff piece about all the public services that could have been provided with the revenue from the capital gains tax, if the government had had the courage to introduce one starting this year.

Given the extraordinary gains currently being made in the housing market, it's safe to say that the revenue would have been substantial, and some seriously useful things – like providing free dentistry – could have been done with the revenue (along with some of the less serious ideas canvassed in the piece).
