What salary is considered rich in South Korea?

Excuse me, I'm a bit curious. Could you possibly enlighten me on the subject of wealth in South Korea? I understand that salaries and wealth standards vary significantly across different countries, and I'm particularly interested in understanding what salary level is generally considered to be 'rich' in South Korea. Of course, I appreciate that this is a somewhat subjective question, but I'm just looking for a general ballpark figure or perhaps a range that people typically associate with being wealthy in your country. Thank you very much for your time and assistance.
