Granted, I expect this question could be easily answered, but I cannot find a definitive reason as to why income tax is pinned at such a high rate in the United Kingdom.
I'm not much of an economist, but I do understand the function of national insurance, and I do understand the function of a tax to fund the various essential organs of the state (Monarchy, Government, Parliament, Intelligence Services,and Defense and Protection forces). However, I don't get why, if I earn around 40k (Sterling), a large portion, around 15% (which is around 5-6k), is taken for income tax.
