The concept of Middle Class has changed a lot since Marx: They USED to be business owners, highly paid professionals like doctors and lawyers, and people who had modest inheritances but had to keep working to get by. The Upper Class was pretty much Old Money: People who never had jobs and never would. At best they clipped their bond coupons to send in, but most of them had people for that. The Working Class were people with jerbs: Easily replaced factory workers, farm workers, miners, guys with lunch pails. And the Poor were the people who didn't have or couldn't perform those jerbs, for one reason or another.

These days in America, The Upper Class is mostly invisible, behind their estate walls and guarded gates, in their limos, or their private planes. There are a few show-offs who seek notoriety as a hobby. (IE. Musk and Trump) The Poor are ever with us. The Working class all have been convinced by media and politicians that they are Middle Class, and entitled to owning a house, leasing new cars, attending Ivy League colleges, etc. That's why so many of them live paycheck to paycheck and file a lot of bankruptcies. The "Working Class" label is derogatory, and associated with Socialism. As if socialism wouldn't benefit most of the Poor and Working Class.

That's actually The Big Lie of the last 80 years, not that the election was stolen by [Israeli Space Lasers, Hugo Chavez, election equipment manufacturers, The Deep State, Demoncrats, etc.]. That's small potatoes lying, there. After just two years, it's falling apart and true believers are going to prison.

Educating anyone benefits everyone.
