Crafty I just finished watching a doco I stumbled on about ten minutes ago, then saw this thread. Everyone should have a bit of a look at this might give you a couple of different answers/views as to future taxes and the reasons. Very interesting stuff, especially the second half. I'm not trying to get political or anything like that, this is a pin site, but I found it a good watch.
