Again you just state numbers with no back up. But assuming what you are saying is true (a huge leap of faith here) let's look at it closely. If the top 5% of wage earners pay 50% of the taxes taken in. And they make 40% of the income. That would mean that the remaining 95% of wage earners make 60% of the income and pay only 50% of the taxes taken in. So using your numbers, the top 5% of wage earners are paying more then the bottom 95% of wage earners. Thus even using your numbers you are proving my point. And let's not forget the fact that much of the taxes that the rich are paying are funneled back out to the poor through entitlements, which results in the poor paying even less tax.
Again I don't agree with your numbers. But let's stay on point! The thing you are supposed to be showing me is that the wealthiest people only pay 5%-8% in income taxes. This is what you stated and what you are supposed to be proving.
On top of this you are also suppose to be disproving the fact that the Bush tax cuts actually resulted in the rich paying more taxes and not less as you complain about, the "so called" tax cuts for the rich.
So I will be waiting for your responses.
