It's a good point.

A while back when i was studying at uni, i worked various part-time catering jobs to earn a bit of extra cash. One of the jobs was effectively being a dinner lady in a fancy private secondary school. I had no different contact with the students but as it was a school in the UK i still needed a criminal/background check to scrub their pans.

Compare that to China and i could walk into any school and teach young learners no questions asked.

There must be a balance between the two somewhere
