The answer to this is- badly!
Waste , waste and more waste. Endless admin assistants, committees, reorganistaions and accountants(great).
All governmment money is put into one great pot and the Chancellor divies it up in the way to get the most votes, as is the case with a two party stae.
All these taxes are not hypothenated, otherwise it would be chaoes. Different tax names are just a way of spreading the burden ever wider ever higher. Such is the cost of living in a (relatively ) civilised country.
