Best System Possible

There has always been an owner class who wields the power of ownership over people who don't possess resources. We just started calling it capitalism relatively recently.

There is a big difference between the model of economy in the past and the current one. And that is that for the longest time, the primary aim was survival and personal satisfaction. Our current system is different in that it requires constant growth. You can never produce or consume too much. If the economy stops growing, that is a catastrophe. And there were obviously problems in the past and capitalism has also lead to great achievements, but the requirement of constant growth is definitely a problem.
Not quite. There have been many different types of societies where power accumulation wasn't as unchecked as monarchies, despotism or current capitalism. None of them were as deeply interconnected commercially as our societies today, but they weren't isolated things. The Dawn of Everything explores a number of those old societies very well
I don’t think that’s true, the concept of ownership (and more specifically land ownership) was an outcome of agriculture.
A tribe leader did not have the same relationship to their people compared to a slave owner.
True, but even the most despotic feudal tyrants did not actively seek the destruction of the entire planet for money. It is the specifics of our current system that enables the most psychopathic people in our society to control it.

My 2 cents:

I think that saying was about democracy, not capitalism
Bear in mind that US is a capitalist lunapark. Most developed countries understood that social policies are absolutely necessary for people, even though we could call those countries a "capitalist country" or countries "based on capitalism". Just saying that don't take what's happenning in the US as a base because it's not
If we're about to start to brainstorm about different systems - bear in mind that (not all but many) people are greedy, proud, jealous and sometimes assholes. And personally, I have a really hard time to design a system that would handle all those wonderful human treats in some decent way

P.S. I was born in socialist Czechoslovakia and its goal was noble but ... it's amazing to watch human greed and jealousy to take over a system like socialism

Yah and a lot of the time you hear that saying about democracy people say basically 'it's not great but it's better than anything else we've tried'.
I would also add to what you're saying about the lunapark - capitalism could work as part of a larger system. At least I think it could. But the uber rich have decimated the normal checks and balances which are the most important element to any system - not just a capitalist democracy.
Yep this is my understanding.
Most Western democracies have capitalism plus socialised services like health and defence.
I think our only hope is for aliens or AI to take over. Whenever humans form a large group, the worst qualities rise to the top. This is how we became the dominant species, but we don't need it anymore.

Nah ... earth has seen worse - massive hurricanes, global volcanic eruptions, giant shifts of plate tectonics, global warming, global cooling, snowball earth, endless rain, oxygen rich atmosphere, no atmosphere, asteroid impacts, environmental/ecological collapse, planet wide extinction events, gamma ray bursts, cosmic radiation, solar flares

We can just add the human species under capitalism as a small footnote to all of it.

If we don't try to save ourselves, we'll just end up as a small thin geologically odd layer in earth's history .... alien archaeologists in a few million years will see the K-Pg layer that wiped out the dinosaurs and then this thin weird radioactive layer of mismatched minerals and material that lasted for a few hundred years.

I don't think capitalism is the problem in itself. The problem is that approaches such as the social market economy, which puts the economy at the service of society, are being increasingly undermined.

This has mainly to do with the US, which is pushing through its ruthless, unregulated capitalism by any means necessary – and this capitalism does not serve society at all, but aims exclusively to put a few people above everyone else.

Trump is the personification of that: An unscrupulous criminal who will stop at nothing to make a profit.

Capitalism exists to perpetuate the power of the wealthy

I mean... this is not fair. Feudalism is the same thing just with extra steps or.you could even say capitalism is feudalism with extra steps. Theres a short timeframe where capitalism is productive after it gets introduced usually and then it turns into feudalism. And feudalism has existed for thousands of years.

"but it's the only system that works". No one said this. Inventing imaginary enemies to argue against. And all the comments here joining in on an argument against no one. Don't you all feel smart.

"people" say this all the time. people who don't know what the fuck they're talking about, or aren't in their right minds. Usually, these people are victims of propaganda, as the US has spend decades convincing everyone that anything socialist or communist is evil. These people exist, and pretending they don't is almost like ignoring that 1/3 of the US population actively supports fascism.

Yeeeeee feudalism!!!!!
