I've read book written by captain Kocebu, that was on duty to protect Russian holdings in Alaska. They visited San Francisco in 1805 and 1815, and several chapters described life of native people in the mission. He described harsh conditions, hard work, no freedom at all, and very high death rates. Shocking even for a early XIX century naval officer. Once a year, those people allowed to visit their tribes and relatives. And they always came back! So, the real hunter gathers, who had first hand comparison for both nomadic and agrarian life, prefer near slavery in mission to life in the wild.
