I didn't say all physical labour was in lower-tier jobs. I said a lot of lower-tier jobs involve physical labour (certainly more than middle-tier jobs). Builders can earn a lot of money, but they can also earn hardly anything.
My mother's previous boyfriend was the head of a carpentry company and earned quite a lot. He worked with his hands, and I certainly wouldn't class him as "lower class".
