"Overall, we find that America's lowest-earning one-fifth of households received roughly $8.21 in government spending for each dollar of taxes paid in 2004."
But the lowest-earning one-fifth has no net worth.
Therefore, the logical conclusion is that they don't hang on to the money for long.
In fact, in many cases the money is paid directly to middle or upper class professionals such as doctors and teachers, who provide services to the bottom fifth.
Where the lowest fifth spend the money is meaningless. What is meaningful is that that parasites are going to kill off the host someday.
Income is not a good measure of net worth.
Many seniors own their own home yet have very little income even though they may have a modest amount of savings while receiving substantial benefits, particularly medical.
What's worse is they show up on the poverty statistics because of their low income while being far better off than younger people who still have to pay for their housing and have no other assets or savings.
You are complaining that the money is not given directly to the people who never earned it ?
That it is somehow unfair that they "only" receive free services like healthcare and education, and free food via foodstamps and school lunches ?
