An opinion I understand and respect, but that I don’t share. Anyone with sufficient education can be absolutely terrified of the soul-crushing future we need to deal with, but what makes life enjoyable is overcoming any challenge put in our way.
Life is pretty fucking miserable for a large part (perhaps even most) of the world on a daily basis. I doubt they'd share your can-do attitude on this subject.
Capitalism will get changed/fixed. At a local level, move to a sane country ;) At a global one, first realize we are much much much better globally than at any other time in history; we will keep improving.
Even in the USA, we're arguably better overall that at any other time in history; yes, Trump is a step back, but it's just so we can get impulse
Even a basic look at where we are shows this as untrue. Our health care is more expensive, life spans are declining, wages dropping when compared with inflation, housing costs rising. We don't have to dig very deep to see that we are going downhill.
We have problems. I believe they are solvable. But we've got to stop denying that we have them.
Capitalism is just a system to allocate resources fairly. Under some very optimistic circumstances it works amazingly well. But if you forcibly distort the system and don't account for processes that are a net benefit for individuals but produce negative value for society at large then it's nothing but self destructive.
So really, just climate change is our problem. We need a sustainable way to obtain resources to further fuel capitalism and approach post-scarcity society.
At any given point I'm one week away from homelessness or starvation. Having skin cancer is better than having pancreatic cancer - but neither of them are good.
