Nothing is "wrong" with it, but the skill required to be one is much lower than it is for other vocations. This means that there are more of them and so they are lower paid. The perception in society is one that because of this they have a lower value.
From my perspective, people who choose low-skill, low-pay work aren't pushing themselves hard enough. It's great if you're good at it and you are low on money, but if it's your life goal to be a plumber you may be setting the bar too low.
But what if being a plumber gets you all of the things you want in life? What is this bar you are talking about? Not everyone wants to be or has to be at the absolute top of their potential.
There's a huge disconnect between economic value and, well, humanity, frankly. Somehow we've come to worship the economic return of everything over the actual experience of living.
