Assuming that the issue is that these positions weren't remote then if they decided that they're better served by workers that live locally then they're either right and you're asking them to harm their own interests for yours or they're wrong and they're just leaving money on the table for a competitor. If they aren't harmed for giving up a competitive edge then that monopoly power to just ignore the market is the actual problem.

Either way, work visas isn't even close to the most salient problem. Restrict them and who's to say how startups will find loopholes to avoid hiring who we want them to hire. Let's just cut out all the messiness and cut them checks directly. Call it reparations for the coasts ignoring the good honest midwest American talent all these years.
