Its not that hard for a high-school kid to properly fix any bead/stem leak but pride in workmanship has seemingly disappeared from the current workforce.
Weeding through the clowns is a management problem.
I'd say it's mostly a management problem. Too many managers are too weak-willed and too unsupported by upper management. You have to be able to truly assess your workers. You have to give them standards to hit and call them out when they miss. You have to actively assess each worker's skills, and reward those who are doing good. You have to tell the weasels to quit schmoozing up to you and turn out good work. When they complain to the higher ups that you're being unfair, you have to have your documentation ready and it needs to be accurate. Being a good manager is hard work, but there are too many lazy managers who'd rather just collect the check.
