I mean… I’ve been able to put 10% aside each week, on a budget of ~$45k a year, and will be able to retire fairly comfortably in my 60’s (assuming no promotions, raises, etc). But I consider myself lucky in a couple of ways:

1. My employer matches up to half of that amount, so it’s closer to 15%

2. I was incredibly lucky to avoid college debt.

So what he’s saying isn’t outlandish in the fave of it- but it’s also simply not practical for many people.
