This has gotten discussed fairly extensively on Discord. Per IF American Cultivation is about pursuing the American Dream which can be basically anything and varies from person to person. Very individual style of Cultivation. So it's only religious for religious people and can support any world view that can be viewed as 'American'. Including people on both sides of the Civil War following it easily.
Soviet Cultivation as discussed there is, theoretically, entirely communal, with only an external resource ala Orthstirr held in common for everyone who only 'borrow' it for use on projects (including raising stats temporarily)...but you can take some permanently to use it as an internal resource for permanent personal stat boosts, and anyone can basically take any amount at any time with no oversight (beyond people knowing you took some...but not what you used it on). So everyone basically embezzles at least a little.
