@dDST, I was going to say, while the counterfeiters lobby is not very strong, they contribute a LOT to political campaigns!
@Gunfighter06, profits aren't everything. Profits are only the bottom line. What happens between the top line and bottom line can be quite important. For example, the company I work for spends most of its money on employees and that amount of money is much higher than the amount of profit sent to stockholders.
What I think would be useful to know would be the percentage of the upper line, the gross income, that goes into U.S. hands via paychecks, taxes, and such. If I buy a Toyota for $10,000, it isn't like $8,000 goes back to Japan. The question is, how much of that cost of the vehicle does go back?
