So this post is not arguing with anyone, its just stating my position...

Capitalism certainly isn't a panacea for all the world's ills- it is the cause of most of the world's most dire problems. What we call capitalism is why we are hurtling towards a 'Great Dying'.

Capitalism- as practiced in the US, and elsewhere- is highly dysfunctional. It is NOT sustainable. It rewards short-term thinking, it comes with no responsibilities beyond the responsibility to maximize profits.

Supply and Demand is real- sometimes- but often it is an illusion. Cartels can manufacture scarcity to drive up profits (Diamonds and Oil are examples). In the opposite extreme, capitalism leads to the unsustainable exploitation of limited resources.

If you define capitalism as rigorous adherence to the laws of supply and demand, then we do not have capitalism in the USA.

We have a system that allows and encourages the wealthy to game the system. Regulations that the wealthy and powerful find too burdensome will lead them to buy a few congress-people to have those regulations removed.

We have a system that exploits people- your taxes pay for the tax-breaks for corporations, your taxes pay for the food-stamps their employees need because they are not paid a living wage- you help feed their employees so they can continue slaving away for the corporations.

After the upheaval of the pandemic there has been a litany of complaints from employers that 'people don't want to work', no... people don't want to work for slave wages. Corporations feel they should be exempt from S&D- if there is a shortage of workers, then the way to address that is to pay more and offer better benefits.

The climate crisis will not be magically solved by capitalism- it will be solved by international agreements and governments using their power to regulate heavily... with incentives as a carrot and with laws to prohibit damaging behavior.

Capitalism COULD be a great thing, if we actually had it- but what we actually have is a kleptocracy of psychopaths, and it leads to insanity like this:

If you were studying a troop of apes, and found a situation where one ape hoarded a million times the number of bananas it could ever eat, while the other apes starved would you think "Well, that ape must be better than the other apes to have 'earned' such a bounty!"? Of course not! You would wonder "What the fuck is wrong with that ape?!", you would maybe study it to determine what caused such a pathology...
And then... you would shoot it.
