He makes it sound like the USA would be just as well off if big tech companies weren't here.
The US government is basically a ~15% shareholder in all US companies due to salary and other taxes. If they can invest in technology research and build more US companies, then the US government earns a net profit.
I would like to see a breakdown for a major technology company to see what percentage of their revenue goes to income tax withholding, and then see how much government funding went into helping that company come to life.

1. Number adjustment
2. By "income tax witholding" I mean the income tax that the employees pay. If 50% of revenue goes to salaries, and 20% of salaries go to income tax witholding, then 10% of a company's revenue goes to income tax.
