In reality, I would  say every nation needs support. Resources are scattered  across  the globe and no single country  can survive without  the help  of other Nations.  If the figures listed  in the OP, is anything  to go by, I think the media always tries to cover the negative side  of the USA. Currently,  I believe  China is relatively economically  stable  and less  indebted  compared  to any other  country in the world.
