No, it was "trailor" that denotes monetary value. People who live in trailors are not, as a whole, extremely rich. Call them trash. It's the trailor part that makes it a class distinction.
Its a common term. I did it illustrate a point and I'm pretty sure it was conveyed.
If I've offended anyone like Toby, I'm sorry. I did not mean to imply that you are trash simply because you live in a trailor home.
