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.
> what you like to do, what you consider ok, what you appreciate or accept in others.
this is describing a culture
> exactly proof that you view them as lower class than yourself.
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.
"White trash" would be a reference to a culture - beliefs, expectations and norms held by a group of people. Paris Hilton may have acted trashily, but is not part of that culture. The beliefs, expectations and norms that she is working to would be different and probably upper class ones.
If you look at this from a class perspective instead of race (hard in the current media environment) it makes sense.
Rather than focus on the white in “white trash” think about the word trash.
