Class is your relationship to the means of production not how much money you make. The labor aristocracy is still working class despite having better material conditions.
This understanding of class was designed by the owning class to divide the workers into who is better than who so that they won't realize they have the same interests and organize against the bourgeoisie
100%, the owning class is the wealth/capital class. Everyone else is working class. If you need to work to continue to have basic needs met like housing, food, healthcare, education, etc you are working class.
Also disrubtion -> disruption in the first experiences box.
I feel like the huge range in the upper class (106k to 461k) is too large to lump everyone into a single group. A person who earns 115k a year has a completely different lifestyle than someone who earns 250k a year. Whereas the top and bottom incomes of the middle to lower classes are likely comparable in terms of life experience.
