To be more precise, that's not the purpose, that's the means. The purpose is to extract the maximum value out of the livestock. Now, to do that, governments must find the right balance of propaganda, social programs and freedom. It differs for different countries. Western countries are no exception: it's just that people are taught that government serves them, while the opposite is actually true. Government is power and anyone who believes it is there to serve his interest and protect him is a fool.

Not sure if I agree with this. Governments are a necessary outgrowth of agriculture: producing more food than you personally can consume means the population can grow in proportion, which necessitates a mechanism for distribution. The fact that governments can exert power beyond their purpose of food distribution is incidental rather than central to their role.
