Yes and for an interesting reason. I am a member of a minority group. Doesn’t matter which, and I have never seen it as a defining part of my identity, but it has one obvious advantage: my friends have come from a wider variety of class backgrounds than they otherwise might have.
Personally I’m skeptical about multiculturalism, I think it can be dangerous in democracy if taken too far. But the fact that humans inevitably sort themselves into groups does have some upsides. De Tocqueville mentioned the political one: groups are a bulwark to protect the individual from the state. But there’s another: a group which is based on ethnicity, or sexuality, or some other immutable personal condition, or religion, or a political ideology, or even a hobby, is at least not one which is based on money and social class.
This doesn’t really compute. Society would collapse if nobody trusted “third parties”, and your second phrase is just hyperbole.
It’s more complex than that. The issue is money, and incentives, and how power is structured. A third party that you are paying or whose income is uncoupled to the profit motive, and preferably one that has both private and institutional stakeholders - well, if we choose not to trust them, then basically we can’t trust anyone for anyone. That would be a dark place to be.
