Ask HN: Do offshore workers have unfair advantage?

When a company makes a decision to hire software engineering team offshore, they usually use the argument "it's not about saving money any more -- it's about tapping into a talent pool, which is scarce in the USA". Well, if this is the case, should the US government consider imposing some sort of a fee to make sure, that the cost of "talent" to the company is the same, regardless of where it comes from, to make it a fair game.
