The problem is, people see taxation at an individual level - which is stupid in itself, it's society's running costs.
While the rich like to pretend they don't live in society, who do they think enforces the value of the money they have?, who protects them from the poor stealing what they have?.
It's the combined cost of the society you are living in, while I agree waste can be reduced (that sounds all good and well, I've yet to hear an argument for increasing waste).
We could reduce the tax burden on all if we spent less money on wars & other frivolous expenditure, but I don't think we should be cutting tax which directly results in the lowering of living standards for most of the population.
Tax, in a perfect form is the cost of sustaining & keeping standards in a given society to an acceptable level.
For me that means no homeless people, no children living in poverty & an equal start for all.
If we did live in a conservative utopia I'd put good money on a revolution of the masses following shortly after - as like it or not, unhappy poor miserable people will eventually get sick of getting the short end of the stick & hell will break loose.
Giving money to the less fortunate is how the rich of this era have managed to stay on top, if they didn't a revolution would have forced change a long time ago - part of me hopes we do get a Tory government for the next 100 year, at least it will force social change through a revolution (instead of Labour who quell the masses with token gifts/bribes/rewards).
