You gave the impression that, because of your disability, you were barely able to support yourself, I didn't realise that you are actually loaded.
Here is your answer:
We have a lot a high net worth clients, who, believe it or not, give a lot of money to charity (yes, rich people are actually surprisingly generous, who knew). The partners also give substantial amounts to charity. In fact, every single bill that goes out of the office has a small amount added on which goes to a charitable trust set up by the practice which the partners match pound for pound.
If you have spare cash, you are better off giving it to charities who are more likely to spend it on actually helping people who really need it, rather than the Government wasting huge chunks of it on crap.
