•what about the SINless awakened?
Given how rare magic is to start (what? 2% of the total population?) there would be actually very few Sinless awakened given the level of demand for them. Just about any Corp or government agency would hire (and issue a SIN) to any awakened that wanted a job..... And pay them extremely well!
So really, the only sinless awakened would be those that choose to be SINless, or are not recognized as 'metahuman' (like pixies or shape changers in the UCAS)
This isn't generally accurate - many Awakened wouldn't be at all suitable to corp life, and thus wouldn't be snatched up. Further, many are going to end up in things like organied crime. That said, it wouldn't be inaccurate to say that Awakened would generally trend upwards in whatever social strata they find themselves in.
