That's all well and good but we were talking about ditch digging not being a skilled laborer. Of course a plumber or electrician can make good money, especially if they own their own business and manage it well. That is a far cry from operating a shovel though isn't it? You'll also notice I mentioned 6 figures specifically, and while I do know ONE plumber who makes that much, it is because he has a rather large multi-employee business and is more of a manager at this point than a plumber. The benefits I was talking about was the ability to sort of mindlessly put your muscles to work. You can do that with a shovel. Mindlessly working with electricity, water mains, or finishing touches on someones house is likely to at best get you fired and at worst get you injured fairly severely.
