Sorry, but this is both hyperbolic and so low on details it's hard to understand the problem. Migrants, so you mean basically homeless people? Low income, so a big chunk of the problem is that minimum wage is not enough to survive without help? (That applies to everyone, not migrants) What does being black have to do with that? What do you mean the kids have nowhere else to go? There are so many kids with no after school programs or any kind.

Is there actually more real context missing here?
