That's true. I'm not say it's easy work, but it is a pretty good gig. Like I said especially here with the cost of living. It may not be 9-5, and there is a lot of prep work and marking. But you're there 8:30-3:30 with an hour lunch. That's a six hour day with an hour lunch.
I exaggerated a bit, but if that's what you want to do, it's a great job. I wouldn't get into it simply for pay/vacation, but if that's what you wanted to do, it's a pretty good lifestyle. I'm fine with teachers getting paid even more, and focus more on the ones that really want to be there. I think it was South Korea that pays teachers on the same levels as doctors.
