Yeah anything short of meeting the strikers demands is insane. I still can't believe that's not what went down. These are possibly some of the most important workers in the country, and they can't even get sick days.
Of course it is feasible, but the transit corps are only interested in maximizing profit and the government backs them up. They could run these trains with 10x the crew, with full top-tier benefits, and still turn a sustainable profit. But right now these companies are being run as paperclip maximizers and merely sustainable profit isn't good enough for them.
