This is it for I think the majority of trade jobs. A few trades in some positions make good money doing the actual trade, but for most of the industry you don't make great money until/unless you can move into a managerial roll where you are setting up jobs as the business owner or manager. And unfortunately a lot of people never get to that point because there aren't enough of those positions for everyone and a good chunk just get used up as meat for the grinder. Many trades are also huge boom/bust industries and the first guys to feel the bust are the guys doing the ground work.
