It's less visible in Europe, but from where she is, it is more common.
What you say is true but there is another part of the problem I got to see with my own eyes while working with the extremely poor.
They usually start from so low a level that it is almost impossible for them to even make it to the levels common for us.
And couple that with the fact that willpower and strength is not the same in everyone, you get people who are more likely to not make it, than people who do.
And nobody can be objective about their starting point, their luck or the real hard work they did in order to escape it.
This is why I found Steem to give me oversight on what the people do and how the people are, so I get to see if they are "helpable" or not and what I could do in order to really help them.
This is a better view of the problem:
