i don't think you understand what your talking about now. another post said the same thing. trashy is undesirable behavior from people. not acting trashy doesn't move you between classes. You just stop fitting the description of trashy.
>Do they understand how little of their world I’m familiar with? Do they understand how much implicit knowledge they take for granted that I don’t have?
If you have that knowledge, you have the connections to regain your wealth. The people who act trashy, if they would learn to not act trashy, they most likely would change class - have different friends, make more money.
Also, when you call some behavior "trashy", it's undesirable from your point of view. The people engaging in it may not find it trashy at all.
You saying "just stop being trashy" is exactly proof that you view them as lower class than yourself. It's similar to people who think saying "ain't" is somehow less correct than "isn't", or that rap music is uncultured. All class markers.
