What you're effectively arguing is that the US does not require nearly as large a number of software engineers as it currently has. It could exclude more than half the software engineers in its largest tech hub, and still fill all the open positions. I find that a bit implausible, especially given how intensely software companies already compete with one another to attract workers. They're not only doing that out of the goodness of their hearts.
