If we're retraining people to do it, we absolutely should, because we'd be spending significant resources for something that might prove a very short-sighted investment. It might be better to just invest that money into automation to do that same work instead.

I imagine that most jobs that have a 'value' of ~$5/hour don't require much training. Also we could implement this policy tomorrow if we wanted to while automation is still many years out (at best) for a lot of tasks, so the two policies could be run in parallel.
