I agree 100%. It wouldn't be easy though. Humans are inherently selfish and greedy. I believe a large minority are borderline sociopathic as well, whether its inherited or learned idk. We need a system that really punishes and limits sociopathic behavior.
Unfortunately but accurately, capitalism rewards sociopathic behavior exponentially, to the point where you have to at least act sociopathic in your decision making to have a very large scale successful business, or at least never/rarely make altruistic decisions. Otherwise, you'll be priced out by competition that does make the more sociopathic decisions (lower pay for workers, dangerous work environments, whatever to cut costs, etc.).
I dont know how we fix this, but it's certainly time for capitalism to die or be reigned in significantly.
