$120k/yr is a very healthy retirement after you have paid off assets and lower expenses. Yes it’s enough, unless you’re unlucky with health issues which would be a problem if you were at $200k/yr as well.
They're setting the system up so no matter how much people have, they'll get fleeced until nothing's left. There's elder care, health care, etc, all private, all super expensive. They want you to spend all the money you saved and sell your house.
