The Scottish Greens have new leadership who have opined that the tax system in Scotland is "stacked in favour of the super rich", which is a variant on "let's get other people to pay for everything". The additional rate of income tax in Scotland is higher than in England, and is reckoned to bring in very little, if anything. So see what happens. Property taxes could be made more progressive, but again, there aren't all that many very rich people about.

I do like the idea of free bus travel though, and would love Scotland to try it.
