There's also issues with the suggestions. It suggests driving for Lyft or Uber for a cool $28k more a year, but the article linked doesn't seem to account for costs of that work, just revenue.
And why "Uber?" Cuz it's cool? Why not "Starbucks barista" or "shelf stocker?" Because what we're really talking about is "work more" I guess "part time job" doesn't sound as hip as it used to...
Flexibility and "being your own boss" (deciding when you're going to drive by yourself, not with some kind of manager) is important to a lot of people.
Is that actually a suggestion? If you make an upper middle class salary (like a programmer does) and reasonably control your expenses, I think you only are going to miss making retirement if you have an expensive medical disaster or you invest too heavily in the market then sell during a crash to make rent, or some weird thing like that. I'm not sure if $20000 is going to make your difference
