Americas debt , when does it stop?

$14,329,911,872,831 is the amount we are in debt as of today may 10, 2011 . The estimated population of the United States is 310,543,514 , so each citizen's share of this debt is  is around $46,144.61. Now we spend ROUGHLY around 700b-1.1 trillion dollars a year . We are too busy being worlds police that we are over looking the problems we have at our own land . Some thing happens in the middle east we spend our own money to help them out , but would they ever do the same for us? People are losing jobs left and right . Americas unemployment rate is around 8.8 percent and why has it even reached that high? we spend so much money over seas that we cant even help ourselves . People in trouble in Africa? let them be in trouble they did it to themselves  , Africa is supposedly  where we all started and and you take a trip there you feel like your in year 1 all over again . its crazy how  uncivilized they are even though they were the first to populate the area . If we spent the money on things like greener products , clean energy , renewing our infrastructure , free Medicare we would be a thriving , not depending on anyone but ourselves country . This concludes todays rant . Thoughts anyone?
