I take it you must be sitting at home in tracksuit bottoms all day claiming benefits then because anyone who pays income tax is better off under the last government than they would have been under labour. Care to elaborate more. You seem to be bothered about the bedroom "tax" which indicates you are obviously on some kind of benefits.
Not everyone thinks only for themselves, some care about the sort of society they want to live in and are happy to pay a little more tax or donate to charity for this purpose.
