rate of return on capital

[pms]

CB: Another couple of questions on this.  2/3 of U.S. FDI goes to developed
countries.  Presumably the enormous amount of investment/capital that is
exported to the U.S. from other developed countries comes to the U.S.
because it has reached zero or low return in those other countries. Why is
it the the U.S. direct investment in those other developed countries is able
to make more profit than the capital that those countries send away to the
U.S. ?  Why is the direct investment from the other developed countries in
the U.S. able to make more profit in the U.S.  than the capital that the
U.S. invests in other countries ( because it no longer makes enough profit
in the U.S. ) ?

Paula:  Yeah?
