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.
