One really nice economic factor of the dole is that it disappears at a rate of 50c for each $1 of earnings above $150 and at 60c above $256, so there's no welfare cliff.

This does mean that you're effectively only earning 40c for every $1 you earn in that middle band, but that's still less of a disincentive than just taking the whole payment away above a certain threshold.

I think we could move to a UBI surprisingly easily by giving everyone the dole and then taxing their income a bit more.
