if before we start changing how tax is collected, we should ask why?
I mean, you say collect tax like it's a good thing... but given that taxes collected from me are theoretically spent for things that benefit me, should we not first be having the conversation about what benefits I actually get?
Don't get me wrong; I do think that governments provide benefits - but it's not always clear what they are; nor how big they are: for example, is HS2 a benefit? Spend £45B and encourage, what? People to live further away from London? The ability to 'work' on a train for a shorter time? When only two hundred years after inventing the bloody thing the fact that train companies are pricing to avoid customers suggests that encouraging more users may not be the best approach.
But that was just an example; it gets worse. Every year the Chancellor gets on his hind legs and brays about 'and this will raise a million pounds', 'this will save half a billion', 'reduce tax by a penny in the pound', 'save the average family two pounds a week'... they're all numbers without context, and it's rather tricky for the average bloke on the street to find the actual numbers and how they relate to the real world.
Every few years we are asked to decide which set of politicians we'd like to lie to us for a while, based largely on financial predictions they make which we are unable to judge and which do not bind; we know neither whether they speak sense nor whether they will hold their word. It's madness.
