I'd also like to see things like the tax system be used to make changes to income inequality - both in terms of like for like pay as well as to some extent evening up the pay professions each sex choose to go into. i.e. if you are a woman you get tax off up to a certain amount because society screws over your pay for getting pregnant.
I'd also love to see meat taxed on a trading system where by everyone would get a meat quota that was quite small - if you want to eat shitloads of meat great - go for it - but you have to pay someone else for their meat points.
You could set the level of everyone's meat tokens for the year at a level to raise people out of poverty/or alternatively just to reflect the costs to the environment.
I'll releasing more totally unworkable economic policies soon... :-)
