Like i say, i can see why the rule is in place as at the end of the day our economy needs X amount and it must be raised one way or another and they cant easily tax the poor any harder, but i do feel there could be fairer ways to do that, such as Motorway toll charges instead of road tax, and alternate scales of tax based on how many hours you actually change for. IE: The more you earn per hour, the more tax you pay above a certain level, that way, Mr A Earning £5K per week for 39 hours would pay more tax than Mr B earning £5K per week for 120hrs. That would be a lot fairer, or at least it would on paper with no real thought behind it.
