And so many people just don't understand that there's really 4 classes: poverty, able to live, owner/landlord, royalty. (The USA has the politician class in place of royalty.)
Note I didn't say "middle class". That term originally was the constructed 'rich merchant non-royalty" class that was founded out of mercantilism into capitalism. The Middle Class is now the landlord and managerial class for most of the western countries.
But back to the topic, a Starbucks worker, a IT worker, a sex worker, and a MD all must sell their time and body to live. It's only when you start buying others labor/property cheaply and selling it expensively do you become a capitalist. Anything else, and youre just in the labor class.
