As an above average, but not great, USA born programmer, I say bring as many programmers as possible to the USA. Great one create can help create the new Google, Uber, etc which than create more jobs. More above average makes software companies more effective over all. There are a ton of horrible "programmers" that are net negatives that bring down the average for a whole IT department.
I don't know if you're making a tongue in cheek argument or not, but currently an enormous portion of the tech immigrants come to America to work as cogs in consulting companies or MegaCorporations.
And there isn't any precise way to pick the people who are going to start the next Google- except for the people who already run successful businesses and therefore have the money and influence to emigrate if they wanted to anyway.
So yes, it'd be cool to have all the Job Creators come to America so we could work in their companies, but I see no evidence that would happen.
