Working class means that you are earning a wage/salary and you don't own the means of your value production. Small businesses typically aren't working class, whereas sports professionals typically are working class.

If you want to talk about income levels, "working class" isn't a term you should be using; it's too big of a bucket.

The problem with this definition is that even CEOs at big tech giants don't own the company (in the vast majority of cases).

Very valid point. One could extend this definition such that: When someone has enough wealth to make a comfortable living passively, they're no longer working class. I think that should sufficiently account for this.
