There's the ownership class, and everyone else.
If you are a landlord, company owner, or in any other way your income comes…
a) Directly from exploiting the labor of others (i.e. profiting from ownership of a company)
b) From little other than owning an asset such as stocks or real estate
You are in the ownership class.
You can have significant income from both a job AND asset ownership, but you're still in the ownership class in that instance in any way that matters to a workers' movement.
Everyone else, even people making 200k per year, are just one bad day away from crippling debt and/or homelessness. They may have a 6 month buffer if they have savings, but that can get wiped out a hundred ways. They may be happier and comfier, but again, they are at the whims of the ownership class, who do not care about them.
The main difference between 20k and 200k (that is relevant to this sub or workers' movements) is that 200k has a much easier time joining the ownership class. However many of them make the conscious decision not to because they think it's immoral. Furthermore, this is heavily discouraged by the ownership class, and just making a lot of money doesn't automatically qualify you.
TL;DR Don't judge a person's true interests on what they make, judge it on how they make it and what they own
