At a certain point automation becomes so efficient that it becomes unprofitable to produce certain goods because they can essentially be made for free. So then corporations don't invest in it and so it is no longer produced. It's already happened with other things, but this is somewhere where the public sector could step in.

It's tricky I don't know how it would be best regulated, but companies are run like totalitarian dictatorships. Large companies, especially public companies should be regulated to benefit the people and the workers. Right now publicly traded companies are incentivized legally to maximamize profit regardless if it's at the expense of employees, the environment and citizens. Maybe federally mandating a coop structure for businesses so businesses are run more democratically could be another solution.
