This is liberal arrogance. Don't worry, most of us educated in the Western system were brought up this way. It took me years to get through mine.
The answer is: be humble, your trust is not necessary for you to learn about materialism, you have no place worrying about USING it yet when haven't even spent the requisite time learning about it.
An ananolgy might be an undergraduate dismissing linguistics after a primer on Wittgenstein. They never read a full text of Wittgenstein, they never read the debate between and among linguists, and they never struggled to understand what was actually being said. They just used their naiive undergrad vibes to be like " that sounds dumb" and ignored it for years, or forever.
You don't have the privilege of us trying to convince you because you haven't bothered to spend the time reading and learning enough to even make a meaningful post on the topic.
Don't worry about whether or not you trust it. Go in humbly, learn, evaluate it, get deep, keep questioning it, read the debates. Don't ask for vibes to counter your vibes.
No investigation, no right to speak.
