I seem to have a lot of apps from folks wanting to be born chattel only to have climbed their way out of the slums.
Unfortunately there is no mobility, upward or down, when it comes to status. It's the inherent unfairness of the system. There are ways for Shareholders to find their rights taken from them, however (a bit from our faq):
Can my character fight for chattel rights?
Yes, but there will be consequences, and it will be harder than you think. Chattel are viewed as being less than human. Brutalizing them and using them has become so normalized that sympathizing with them would be considered not only heresy, but madness. Shareholders would risk being labeled mentally unfit, having their powers stripped from them, and being institutionalized. Elites could face devastating fines, imprisonment, losing their jobs. What's more, the fact that they are worthless, and that they are chattel because of divine law has been internalized by most chattel. Telling one they deserved a better life would likely involve a lot of scared, confused looks. They might contact the authorities on you themselves. It is important that you conspire very, very carefully.
