Can we please get over this idea that founders conjure jobs out of thin air. Startups and the jobs they create fill a niche in the economy. That niche is the product of the wider world, not the whim of a founder. Even where a startup does create apparently "new" jobs, they often result in other jobs disappearing elsewhere (see uber v. taxis). Bringing in foreign investment is great. But we don't need to treat well-funded founders as a special class beyond the numerous advantages that already come with being well-funded.
I would hate to be the new hire at a "startup" which turns out to be an immigration dodge, a means of getting a group of founders the necessary documentation. There are already other visa categories for such things (EB-5).
