Are teachers highly paid in Korea?

Excuse me, could you please elaborate on the salary structure of teachers in Korea? I've heard conflicting reports about whether they are highly compensated or not. Could you provide some insights into the average salaries, as well as any potential benefits or incentives that teachers may receive? Additionally, are there any notable differences in pay scales between urban and rural areas, or between different levels of education, such as elementary, middle, and high school teachers? I'm particularly interested in understanding the financial aspect of teaching in Korea.
