Eight was actually the minimum I was hoping for, so I'll be working on an OoC. I'm currently at work though, and my phone is nearly dead so I must leave it to charge. I will return later, with goodies too. Also, yes most of the MP would be well off financially. You could go with the idea you gave, or maybe they lived in the third ring, the last ring MP are recruited from, making them relatively poor compared to people in the center and second ring though still not as poor as those in the fourth and fifth rings.
