I’m too European to get it. What is the message?

You don’t have homeless people in Europe? The message is that not all homeless look like the guy in the first panel. There are all of these “invisible” homeless that go unseen because they don’t fit the stereotype.

We do have homeless people in Europe/Germany.

Thank you for your explanation. My problems understanding these panels were

• The kids in the panels. TIL, it is possible for kids to be homeless in the US. It’s hard for me to imagine that a society would let there kids be homeless. We got kids who fled from home and do not accept any help, thus being homeless in Germany as well, but these kids are on the run, not in schools or in cars with their mother.
• The idea that a woman having a car and a kid might be homeless is totally alien to me, as well. The only possibility I can think of how this could happen is if she just ran away spontaneously neglecting all help she could get – that does happen, of course, and probably I’m just too naive.
