There are transferrable skills, but they're transferrable in the way that making buildings out of LEGO is transferrable to building actual buildings. There are large differences and a whole host of other challenges.
[I'm not a teacher, but I have a few friends that are teachers or training to be teachers.]
Sorry for going off-topic but I come from a small school and I don't understand how it is acceptable for class size to be huge (40+ students in a class is considered acceptable). I mean I get it if the class is led by someone extraordinary like Richard Feynman and everyone wants to be in his lectures but as others have said most teachers are not celebrities.
Plus, I don't think just because someone went through the motions of getting a license thirty years ago and all the certification conferences means that they are decent teachers today.
So basically we have no friends. The unions are not our friends obviously but the people who want to break teacher unions are also not our friends because they want to profit at our expense.
The problem is that education reform is an common empty promise in politics. Education is underfunded in most countries, and better funding (and then more education for teachers) would be very helpful.
Babysitters don't have to get the kids to DO anything.
Saying these are the same is like saying a manager in a business is only supposed to check if employees showed up and clocked in.
Sure, some managers are that bad at their job, but it is also very clear that their job is supposed to be much more than that.
Same with teachers. Getting 30 children who did not choose to be there to actually DO something is a very different skillset than babysitting.

Otherwise, there are two basic possibilities depending on the kid's parents. Either the kid is expected to try and DO something (and does), or the parent only expects child care. In the latter case, avoiding willful destruction and interruption is all that is required … tada, babysitting!
The manager analogy doesn't make sense because managers are much more directly accountable for whether the employees achieve anything for the company while clocking in. If managers' mostly subjective assessments were the only tangible output of employee time and other impacts were felt years later and weren't directly ascribable to an individual manager, then maybe the analogy would work.
