Final answer:
The statement is false; foreign investments can generate significant revenue and international sales can match or exceed domestic sales in a globalized economy.
Step-by-step explanation:
The statement that foreign investments don't produce a lot of revenue and mostly domestic sales exceed international sales is false. In today's globalized economy, U.S. businesses, as well as those around the world, engage in substantial amounts of international trade and investment. As per the information provided, U.S. businesses sell trillions of dollars' worth of exports and also invest trillions abroad.
Equally, foreign investors put significant amounts of money into the United States every year, including major purchases of U.S. federal debt. Thus, foreign investments can generate significant revenue and sometimes may even surpass domestic sales depending on the industry and market conditions.
