Is having 1.3 billion KRW in net assets still considered impressive??

Net assets per household
of 1.3 billion KRW puts you in the top 10%.
If we assume a single person has 1.3 billion KRW without a family, wouldn't they be able to live a fairly comfortable retirement???
If you are in your mid-to-late 40s with 1.3 billion KRW and an annual salary of over 100 million KRW, it seems like you'd be financially secure,
but the majority opinion is that you still can't even afford a single house in Seoul.
Of course, I don't even have 500 million KRW.
