@dadofthreeboys I was replying to someone who said that my lifestyle growing up was "working class," but my family isn't working class. Working class refers to jobs that require little education (less than trade school), are physical, and labor intensive, such as factory work. Some trades could fall under working class, such as landscaper, and some jobs are trades but might not due to more education involved, such as electrician/plumber/etc.
Poor and white collar workers might be lower or lower middle class. You can in contrast be blue collar and be upper middle or even upper class. Blue and white collar work only refers to the sort of labor you perform, not the wages you take home.
Class is partly about money, but working class is a term taken from Marxist theory, and is also known as the proletariat. It is a separate term from the socioeconomic division of society between lower, middle, and upper classes.
