There is no such thing as 'class'. Don't buy into these bullshit categorizations.
This.
It is a method of dividing people to stir up resentment in order to keep their control in place. The athoritarians like to divide and control in order to keep their wealth and power. If you are talking about the US, look at income statistics over a decade or two. The "rich" one year are very often not on it ten years later. It is very fluid and that is the nature of a free country.
I wholeheartedly agree with this. If people lose their money to they stop being upper class? If the poor earn their wealth do they suddenly transition into the upper class? It's just another form for people to discriminate.
