Apprenticeship. Good small time subcontractors show up to the job themselves but train others to do most of the work. Subs I worked with had pretty healthy markup over what they were paying their workers (>100% when invoicing hours). The catch is they all had spent years learning the trade, and that part is definitely dangerous. I saw a guy ruin his back being over eager pouring concrete.
