Capitalism is just basically free trade with free will, it's like a current of water flowing. What we as civilized humans need to do is regulate it so me minimize damages and maximize gains for our species and planet.
Meaning we regulate things like food industry; selling poison to customers should be illegal and regulated, destroying environment should be illegal et cetera, you get the point?
Irregulated industry will of course maximize profits and minimize expenses as any profit looking company does and we end up like in the old days, arsenic in candies, poisoned milk, lead/poison in wallpapers making people mad.
No, there's 3 forces: the people, government and companies.
Companies are should not be viewed as anything else than tools, they are there to make money, and will form monopolies (very unhealthy for free market capitalism, removes competition) if they can and don't care if they are enslaving people and keeping them in horrible circumstances.
Horrible governments also exist, a bigger government is not usually there to maximize the interest of its people, instead the governments is looking out for itself. And if we are not careful, the government will work together with corporations against the people, known as fascism.
What me must do is make sure the benefit of the people is what matters, and have a minimized government that doesn't control your life and instead keeps the companies and itself in check. Your freedom is not theirs to give, their job is to make sure nobody infringes your freedoms.
What we live in today is something completely different - we have central banks with immense powers to print out money and manipulate everything, and in the end we live in a strange planned economy capitalism where the rich have socialism; the tax payers ensure to pay if something would happen to their fortune, this is what we saw during financial crisis of 2008 and again in corona crisis. We printed out money and that transferred to the pockets for those that have the money to own stocks, and now we will see the price increase in prices for everything.
What I would like to see, real free market capitalism (still regulated though) where some unelected bankers, byroucrats and politicians behind closed doors control the system. There should be minimal intervention and only to remove harmful trash, like companies poisoning people.
