If I were a billionaire I would be investing hard into opening a series of farm hotels for remote workers all over the world, with some sort of membership system that allowed folks to stay in any of them without hassle. I would provide high speed internet, small office rooms and vast contact to nature, healthy food options, sightseeing deals and that sort of stuff, all of them at locations chosen to keep the city centers at arms length - avoiding the city noise but not going too far from it.
I’m sure this will eventually be a common business, not many years from now (though probably with lower standards than what I described).
They don’t really need to be high skilled if they are already employed. They’d be bringing money with them, so its basically an expansion on tourism. Opening opportunities for people to travel without having to disconnect from work. It’s specially useful to attract Americans who notoriously don’t get to take vacation leaves.
