Try actually defining capitalism in a way that doesn't apply to basically any random society since the dawn of agriculture.

Stuff like people buying and selling items using a currency for a price the individual chooses has been common to basically every human society we have written records for.

The formalization of the process of buying shares in a company and receiving dividends/profits as a result is a bit newer, but the general concept of "I give you money, you use it to make something and sell it then give me money back" has been around for roughly the same amount of time as currency itself.

Anyways, my point is that there is a lot of things to criticize about our current world/economy, using the term "capitalism" while doing so is too vague to be useful in any way.

(Communism/socialism does have more of an actual definition, but very few people are aware of or use it, so it doesn't help all that much).
