It's Sunday, so it's rant time. Simple solutions to the UK's problems, and by extension, the world's: Tax the banks, charging them interest on the money they store instead of putting it to use in the world. Make government purely based on proportional representation. Bring in the ‘Tobin tax', charging micropayments on each and every share transaction in the stock market. Operate a more lateral approach to Afghanistan involving less troops and less expense. Re-nationalise the transport systems and the utilities (water, gas and electric), thus substantially reducing the costs. Scrap ID cards. And most importantly, scrap Trident. For the cost of one nuclear Trident missile you can build a hospital or three schools. Invest the money saved into healthcare, housing and renewables. Make car ownership much more expensive, and promote community rental fleets of hybrid or electric cars. Close the churches, mosques and synagogues and turn them into community centres. Give everyone free broadband. And teach astrology and philosophy in schools - within two generations we will have the end of warfare. I'm going to get into trouble for this one, aren't I?
