Thanks to the RG for writing this, a lot of good information. People, like some of those commenting here, may be incapable of getting it because of their self-interest in not paying taxes, but hopefully elected leaders and the majority of the interested public will get it.

To clear up one common misconception, anyone without a home is in fact homeless, even if they're staying in someone else's home. That is always a crowded stressful situation for everyone, and will not last long. That's why kids in that situation are considered homeless. Unstable living situations are hard on kids, and make it more difficult for them to learn in school.
