I am in favour of a fair tax system (though mostly in relation to affordable housing), but it's hard to argue that VAT affects the poor significantly. Essential electrical goods have never been cheaper. Washing machines, toasters, and even computers (arguably essential these days) are all available at bargain basement prices compared to the past, and the further back you go the worse it gets. We really are better off than we used to be... and I talk as someone with below average (or even median) earnings.
So it's important to keep a sense of perspective. We have blurred the line between luxury and essential thanks to 20 years or so of expanding virtual wealth (ie national and personal debt), and perhaps it's time for all of us to sit back and work out exactly what the difference is between need and want.
Ultimately the best way for the poor to stop being poor is to work harder, stop buying junk, and -- the secret weapon of the middle classess -- stop having kids so young. The latter concentrates more money in fewer generations... though in recent years the benefit system has expanded to make up that gap to an extent, which is unfortunately part of the problem.
We are going to be living through some very "interesting" times, and I think we're all going to have to think a bit harder about things we used to take for granted. Especially those who don't have the benefit of previous experience of really tough times in this country.
