Citing a bunch of statistics about non-poor people who work multiple jobs, and irrelevancies like multigenerational configuration, are not really supporting the comic.

It's quite true that people with lots of money (like Richard's parents) tend to work long hours. And 5% of the workforce - most of them non-poor - might work 2 jobs. That's almost exactly the opposite of what the comic portrays.

Similarly, attributing things like poor people getting sick more on things like a damp house (or otherwise lacking money) is simply wrong. We now have an actual randomized trial to demonstrate this. http://m.qje.oxfordjournals.org/content/131/2/687

Most likely some third hidden factor (for example low conscientiousness resulting in poor work habits and poor health habits) causes both poverty and poor health.

I'm not disputing the idea that some folks have a leg up on life. I'm simply disputing a comic that wildly misleads about the actual nature of that leg up.

Also, on the thing you are "not even going to bother to search", the question is not whether poor schools have bad outcomes. The question is whether those schools are significantly worse themselves - i.e., if we were to reduce class sizes, would outcomes improve? (Most studies suggest that small class sizes - like virtually every educational intervention - would barely change outcomes.)
