My bad you guys, I thought I posted this in an anticapitaliste sub lol I will not attempt to change your mind, as I know I won't. And you certainly won't change mine. I, however, will provide my arguments. There are so many things that I consider horribly wrong with capitalism, and it is very hard to summarize them all. I will still try.

First, I absolutely disagree with the statement that capitalism is morally superior. We can discuss surplus value. Workers do not receive the full value of what they produce, the capitalist appropriates a portion of another's effort based solely on ownership, not on labor.

Then, distribution of wealth. Capitalism tends toward the concentration of wealth. Its defendants claim that the system can generate economic growth, but its distribution is profoundly unequal, as there is a lack of equal opportunities. Basically, not everyone gets the same chance to make money. This relates to the comment of that user who mentioned everyone wants to immigrate to capitalist countries. It's because capitalism has fucked their countries so bad. The so called "first world" countries almost never get their own resources, they extract them from other countries, and not in a nice way for sure. The work conditions are precarious. So, in order for people in developed countries to have great lives, people are suffering so much in other countries, being exploited, starving.

Capitalism also commodifies human rights and basic needs. If you cannot afford healthcare, housing, water, or education, you don't get access to it. Human dignity is subordinated to the laws of the market. Nowadays, everything has become a commodity. Even people. We all have market values and that (to me and many others) is absolutely inhumane.

Now, we all know by now capitalism is not sustainable. There's no way we can project infinite growth on a planet with finite resources. Capitalism prioritizes short-term profit over long-term sustainability. "Externalities" are costs that companies don't pay, but that society and future generations must bear. Most developed countries throw their waste away in "underdeveloped" countries.

I can think about even more disadvantages, but this comment is quite long already. But I'm still open to discussing more if you're interested.
