Well you might be missing the point. The point is that human advancement is directly tied to human involvement.You seem very convinced for some reason that if everyone on this earth had access to more money, we would somehow have found the cure for cancer and aging and solved global warming by now. I have nothing to say to that, save that it’s all hypothetical, so I find it hard to argue for or against it either way.
The more wealth inequality the less human involvement. The more wealth equality the more human involvement. If you take 1 billion humans and put them on a planet, and you take 5 billion humans and put them on a different planet, the planet with 5 billion humans will be astronomically more advanced, faster.
Our problem is that as we have grown in population, we have also greatly increased wealth inequality. You can look at charts of wealth from say 1900 onwards and it’s staggering how much it’s grown. If wealth had remained neutral then literally billions of more humans would’ve had opportunities to get education and advance the world. That is what I mean when I say we would be 30-50 years more advanced. Look at what happens when the entire planet Earth has a problem: COVID-19. They fix it. Unimaginably quickly. To have a vaccine that effective, that fast is astounding.
