'Proof' of Empire

[Labor Shall Rule]

I was wondering, does anyone have any data or empirical evidence that points to how most capitalist investment in overseas markets comes from the United States?

Most FDI while it comes from the Triad of Europe/N.America/Japan is largely confined within that Triad. This is where FDI comes from; http://en.wikipedia.org/wiki/List_of_countries_by_FDI_abroad

So yeah US puts most in but at the same time look where it goes (and look how much they receive);

Global North dominance is instead exercised more so through other means, such as unequal trade/subsidies

I don't have any statistical evidence but I was wondering how empire-deniers explain why workers in rich countries earn more than workers in poor countries for the same labour.
