I'm not sure I ever had faith in capitalism. There's just some shameless and obvious wrongness about it, like watching the Disney dog skinning movie and believing Cruella de Vil is the protagonist. It's always felt like thinly veiled post-hoc justifications/cover ups for might makes right, victim blaming, kleptomania, etc.. Lot's of mental gymnastics for "it's in my hands, therefor should be mine" and "there's nothing wrong, you shouldn't do anything to fix society". It's like having faith Santa Claus is real, past the age of children, you just have to be gullible or benefiting from others being gullible to believe this.

Although in debates most people argue like they have this weird idea that capitalism means personal freedoms like the right to flea markets, as opposed to the ideology that justifies the authoritarian control of society's capital concentrated into the hands of the capitalist class.
