If an employee makes enough money they aren't middle class. And if a CEO is getting paid normally then they're an employee too.

Also I was thinking in terms of math applied to percentiles and other statistics, which don't change with inflation.

Are you really going to say it's crab bucket if I say a number like "a million dollars" and say it should apply to both income and capital gains? Maybe even a lower number for capital gains, if I'm being feisty?

I actually like to use worker class and owning class. Bosses (including CEOs) are apart of the owning class. CEOs being employers is just semantics, they are still bosses, and is the reason I use the word workers to make it clear.

Well paid google workers are still workers and deserve our solidarity. Making a distinction among workers between lower classes, and middle and upper class only serves to divide us, destroy our solidarity, and for our bosses to keep exploiting us.

How many workers get more than a million dollars, keeping the same example threshold? It barely affects solidarity.

And why shouldn't I have some solidarity with an owner of a business that has 30k more assets than debts and personally makes 40k a year?

I think income and wealth are better distinguishers than the role you have.
