We should have a welfare state that provides for people who are retired (just like we should for other non-workers, like children, the disabled, students, etc.).
When you’re always in danger of going broke from a medical condition or emergency, $80k isn’t enough to feel secure. The system is designed so it’s never enough but you can reduce risk with more.
2 million is barely enough to retired on in a country without a social safety net. But one of the points of taxing people is to provide that safety net.
