"You can't just dive in and meddle with a system which keeps food on everyone's table"
No doubt that the capitalistic system has been a wonderful way to solve the problem it was accelerating itself in the ~200 years of its broader existence. Just the side-effect it causes are too dangerous as we can see with the drastic climate change gaining in drive. So it's not a question of "can't" anymore but a choice between "must" or "will be forced to" 🙂
