Wow, what a topic! I'll add a few more of my two cents worth then I think I'm done. Whether taxing the higher incomes is fair or not, I personally don't mind giving up more if I have enough to live on. How much money does one really need to have? Happiness alone does not come from money. I would be happy to give a higher share if I know it's helping someone out. If my taxes go to irresponsible spending, no I'm not happy with that.
People that ask "How much money does one really need to have?" really chap my a$$. Its none of your business how much money a person thinks they need as long as we live in a free society. You just worry about your own conscience and let others worry about theirs.
this hits close to home as one time I was part of a law suit and the opposite side lawywer asked how much insurance I had.....he already had my income statement, and you know what he was fishing for!... I told him I had none....he hasked why...I told him I couldnt afford it.... he said :"with that income I cannot see how you cannot afford it?:"
I asked him how HE could tell ME what I could afford or not, thats MY decision to make! he shut up.
