In his influential book on Universal Income, "Utopia for Realists", Rutger Bregman discusses this at some length (referencing the same study).

I have to say I have experienced it myself, and not having enough money for the essentials is so all consuming that you cannot possibly perform well at work and make good life decisions. I have succeeded at work under these conditions, but I gave up everything else, hobbies, leisure time, and worse of all time with my children. Maybe my kids will do worse in their exams because I didn't have the mental capacity left to see where they needed help. Maybe this will make them poorer too.
