The US poverty threshold for a family of four is approximately $22,000 a year.
Earning $22,000 a year places you in the top 10% of households worldwide.
Seems like a disconnect to me!
The US poverty threshold is much lower than what allows people to receive public assistance of some kind or another. In our area, a family of four can qualify for help with utilities, health care (of course this will be changing), and food, if they make less than $45,000 a year.
...and it's not enough!
