It is my opinion that we should not punish people for working hard by taxing them more. If you tax people more then they will spend less and create less jobs. If you get less tax then you spend more and pay more VAT and people that are rich will feel less need to move away so there is very little difference.
Tax is a big topic at this time because we are close to a general election and tax always pops up. It may be the best to leave it the same. I would consolidate all tax into a flat rate universal gains tax and just find ways to save on spending. You can't keep raising tax because it would become absurd you would create a world of frivolous spending and difficulties.
Like all things in this world, there is always a level of complexity that comes with the topic and my simple answer would never complete the equation.
All I can say is that we may be able to find inspiration from other countries because they may have found the best formula.
