15 years in I have built systems from scratch and done menial janitor work. I don't think its fair to say that that it isn't complex, some shitty work can be really complex due to subtleties and it would take someone with a fair bit of experience to fix. If it was so easy there wouldn't be a shortage of tech workers and our wages would be way lower.

Im not saying this type of work cant be complex (again, usually because “someone fucked up somewhere”), but it certainly doesn’t have to be.
