- Seems to me a reasonably comprehensive and certainly clear summary of relatively accessible facts. The comparison between China and the US serves some limited purposes, if only to make US Americans feel better about not having gotten everything quite as wrong as the Chinese Communist Party, but it's not clear to me that comparison is apt, except on the absolutely a-cultural basis of "human rights" comparison. Mobility of persons, considered as an abstract topic, has a somewhat different history over the last, say, two thousand years in China and in North America. To begin only from the current state of constitutional law and residence regulation is to make an implicit assertion that history is irrelevant. I'd like at least an argument about that.
