Two Way Street called Trade

HAL R. VARIAN writes in New York times in the article : What Goes Abroad Usually Comes Back, With Benefits
The article essentially tells us that any 'trade' is a two-way street.

The money paid to foreign producers, whether businesses or workers, typically comes back home to buy domestic goods and services, thereby generating domestic employment. That is true whether it is European companies paying American biotech researchers, or American companies paying Indian programmers.


Think about it. If Oracle sends $10,000 abroad to pay an Indian programmer, then that money either finds its way back to the United States or it doesn't. If it comes back, it can be used to buy American goods and services, employing American workers. If it doesn't come back then it's even better from the viewpoint of the country: we've sent them paper, while they've sent us valuable goods and services.
