With all the food recalls, I'm sure plumbing is a high demand job.

Jokes aside; trades suck. If you like hot ass heat, cramped places, constant injuries, buying your own tools, ruining your body before you reach forty, and annoying customers; then it's the job for you. This is an anecdotal take but yeah it's not fun. I wouldn't be exaggerating if I say I wish I did anything else for the last ten years. The money was good but the added pain isn't worth it.
