If you looks at history “regulated” capitalism eventually deregulates because it’s in the interests of the rich to do so and even “regulated” capitalism has exploited the global south for decades and decades. I reject your idea that a few will always rise to the top and be malicious with the power, but even saying that’s true how is that any worse than the current state? I would rather at least try to find a new way to do things than resigning the world to having this be its peak where millions are hungry and destitute.
