This definitely implies a questionable decision.
> Or you ( or a member of your family) could have a debilitating/rare disease and your insurance does not cover all the treatments for it
Sure, there could be rare cataclysmic events that drain you of your financial resources. That's not really on-topic to what the discussion is about though.
> Or you could have been fired and opened your own business and your partners fleeced you out (ask me how I know)
This is 100% a bad decision. Do not take money out of your 401k to start a business.
> Or you live in a country where salaries are below 45 k /y.
Then you likely live in a country where the CoL is significantly lower than in the US and the dynamics of retirement are very different. I'm speaking 100% from an American-centric point of view.
> You have a very naive, simplistic and privileged worldview so I hope for your own sake you never have to leave that cocoon.
I'm sorry my short internet comment on a technology forum is not comprehensive enough to account for all potential scenarios and nuance. I grew up in poverty, and I'm going to do everything I can to prevent myself from ending back up in that situation.
