The class distinction is owner vs worker. Do you have to work? You are working class. Do you collect money from people because you and your family “own” an essential pillar of society? You are owner class.
You need to consider that most jobs out there are simply things that need to be done, not things that people are passionate about. Getting a higher eductation and a complex job is something for which I consider myself very lucky. I was born with all the opportunities to do so. Despite these privileges, I acknowledge that the people doing the fundamental, low level jobs deserve adequate compensation to lead a happy life
