where you can enter your income and expenses and get a taste of the benefits of a transaction tax as proposed in the USA in 2014.
Bear in mind my arguments - Just switching to the tax would be impossible - too much lobbying and scaremongering on the dollar side. But argue for a next to zero starting rate, get the data flow going to government departments ( and through them, to social support bodies, business groups, and even investment banks ) and then debate the rate needed to replace all other taxes, and you have a chance to make this change to a fairer system.
