The main topic of ch 23 was inequality across the world. Inequailty has become more visible since the world has become more connected, since having trade across countries shows what countries have more than others. Now people aren't just unequal in their own country, but unequal on a global scale. Inequailty also isn't just monetary, access to certain resources like water or facilities like schools are unequal in distribution. Unfortunatly, everywhere has inequality, but now we are able to understand where we stand and what we don't have that others have in abundance.
The Maya Coffee farmers show certain benefits of free trade. Rural farmers were able to set a minimum price they were paid for their coffee that allowed them to not go under in times of uncertainity. Due to this, they have stability on the market. However, this is just the minimum they can go, and it's not exactly enough to prosper. They still get so much less than the people selling the coffee to the average consumer. Fair Trade allows them to survive, but it's still not enough to solve the issues of a global market.
The Colbalt Pipeline reveals the disconnect between the consumer and the production of their products.

I love my phone, my laptop, ipad, but sometimes you really need to sit down and actually look at where your products come from, and if you really feel comfortable supporting this.
