My bigger concern about the first chapter is that income inequality is actually a very advanced topic. That requires a lot of technical analysis. At the very least you have to discuss the concept of power laws which income distributions fit quite well, and is exactly what I would expect without direct government intervention. Making it the first section of the first chapter, really trivializes the topic.
2) I'm sure plenty of people who do not understand power laws are able to comprehend economic concepts around inequality.
Well, sure. But wherever a power distribution pops up, there's a chance that a complex system (small-worlds network) might be hiding in the gutty works. Which means that obvious "fixes", which might occur to the novice taking the class, to even out the distribution, could well have unpleasant side-effects. Up to and including complete/utter collapse.
Now - if the final chapter were something like: "Now, here's why everything we came up with in Chapter 1 was wrong.", that might be an interesting bookend.

* More likely to engage in deception for personal gain
* More likely to rate greed as 'moral'
* Will keep an average of 13% more money for themselves in a game of 'fairness'* *
