This makes sense multiple perspectives: it's good for the climate to not make people burn gasoline every day (though this point may be lost on some people) and it's also good for the local community - both the employer needs to step his game up to assist and train people more since talent pool is limited and locals also need to step their game up since there are only so many local employers around (assuming all prefer to hire locally).

Going this way, if this were a law, would also prevent employers from treating people as expendable. Flying people in from across the globe because they are marginally cheaper than the local work force never made sense to me.
