We don’t because when you nationalize Pfizer and start drafting people to work there people get upset and you kill the golden goose like Stalin did in the UkraineSo yeah, difficult but not hard. If money isn't a problem, then capacity is a choice. Doable but we won't.
Climate change is the same. We have every excuse in the world as to why we can't, until we will have no choice but to do far worse, to ourselves, because we no longer have a choice. The poor (everywhere) will be the worse impacted. BTW, in a blue sky world, there is no need for any person on this planet to be without food or shelter or access to reasonable health care or education. Unfortunately we're in charge.
Similarly when you take away people hamburgers, shoot their dogs and tell people to sterilize their kids they have a tendency to get the pitchforks. Why are you guys here if you care about global warming? Why did you have kids? Why are you driving (the horror) to soccer tournaments?
