Your point is well taken. However, we do have lots of talent already here (many are ones already here on various student and work visas). YC is limited to a narrow set of people that can "afford" the process. I do not buy the argument that this implies we need to increase the pool of eligible applicants with a special visa. Perhaps YC will simply reach its limits. Thats ok, there is no reason that something has to keep growing in size to continue to be a success; it could just reach a natural equilibrium.

Is there any evidence that the U.S. does not already have the talent? Or is it only that there is not enough talent that can afford to work at such low entry rates? Please keep in mind that our visa programs that already exist are to fill positions where there is proven lack of skills. They do not exist so the investor or business owners can find cheaper labor.
