I have a friend who works ad a teacher in the UK. He currently earns £30k. For that he works 80 hours a week, has to deal with degenerate children and the arseholes who raised them. Last year he was told he would be “beaten to a pulp in the car park” for telling a parent their kid was en route to failure.
Today he was offered a job in China for the equivalent of £51k before bonuses. He sets off in July.
