If your income comes mainly from your work, you’re Working Class (even if you own you own business), if your income comes mainly from the money made by the money you have (in assets or even “investments”) you’re Owner Class.

Certainly, modern politics only ever divides people in those two classes, with mainstream parties generaly only working for the good of the Owner Class which is how you end up with falling salaries in real terms and growing Asset valuations in the form of bubbles on all kinds of assets, most notably stocks and realestate (notice how most mainstream politicians see the rising of both stockmarkets and also house prices - tough of late, they don’t say it about the latter quite as openly - as being good things).

The single greatest scam of modern Neoliberal Capitalism was making people who own their means of production but still have to work for a living think they’re not Working Class and hence Neoliberal Capitalism was actually working for them.
