Exactly. They probably don't balance anything. Industrial tools manufacturers have the same issues. Sometimes it ends in breaking that hurt both people and the tool, but sometimes it's even more dumb: 'hey, this part is under a lot of friction, has to be replaced after each maintenance cycle, let's buy almost the same at half the cost, the maintenance will be 20% cheaper'. How it end up: the tool require faster maintenance cycle, and in the end, without taking into account maintenance technicians salaries, it ends up 30% more expensive (which isn't an issue for new tools, but quite a big one for tools under initial maintenance contracts)
