>There's very few currencies in the world in which 1M isn't enough to retire. USD isn't one of them.

Unless you're planning on retiring as cheaply as humanly possible, 1M is not enough to retire for the large majority of the currencies in the world.

$1M is enough to "Ramen Retire" in most of the US. If you're willing to eat noodles and make some lifestyle sacrifices, it's kinda sorta doable.

For majority of the world population 1M is amount they will never earn through their entire life. And they live just fine. I'm sure anyone can have a really nice retirement with one 1M, just not in the US.
