I guess I could get by on $1.90 per day for food in the US if I had to, but it would really suck.

But the article is about extreme poverty. People who don't know if they're going to survive the next week or month. In the developing world, $1.90 per day provides just enough security that you're pretty sure you won't starve next week.

It's pretty damn bleak, but the fact is that a lot of people live in conditions where they know they may starve in the near future, and if fewer people live in those conditions, that's important.
