Uhm where isn't it enough to retire? I will retire when I have amassed far less.
5mil is the bare minimum to retire on in the US after inflation considered. You can expect safe income of about 100k a year. That's not really a lot when you think about it. Unless you live in some awful town.
Are you crazy? How do you possibly need a 100k income to retire on? What are you doing, eating steak every night? That is more than twice the median family income in the US.
Considering the fact that Medicare and Social Security are going to blow up, seems about right to me. Medical expenses will be through the roof, so a lot of your income will go just to that. In fact, the best investment a young person can make right now is probably their own health.
