If you want a look at how part of America lives in 2019 you could do worse than watch this 5.5-minute video. In it a 37-year-old, twice-divorced woman, with a degree from MIT, living in NYC with, she admits, no retirement savings at all discusses her finances.
The most surprising thing to me is that she supposedly is grossing $108K/year doing three things: being a Reiki healer--I'd heard the name but knew nothing about it. This piece is seemingly a good, short summary of it. Not for me, but your mileage may vary--being a "part-time" comedian, and running an online course.
