Labour association with poverty

A few days ago, I was out taking pictures all around Arusha. Over here, sometimes we face quite a few  road problems, so going home, the road we usually take was closed down due to construction purposes. So we decided to take a short cut that passes a, well you could say mini village, a dusty, small, crowded place. Driving through this so-called village, I saw many "labourer's" transporting goods in their kokotenis (A wooden wheelbarrow) and realized something.
What jobs can be labelled as "labour work", in other words who are labourer's. So I though of the obvious workers, such as builders, cleaners, farmers etc.. I thought a little bit about their income, and obviously no labourer gets paid the wage of a doctor, or a celebrity for that matter.Now this may not be in all cases, but do most labour workers have a low income? I found this quite interesting because personally, I would say labour work is physically more difficult than other jobs, and yet, it is still paid with a low income.
Here are some of the salaries for labour workers who work for US brand names (dollars)
