You need to remember minimum wage is 1500 EUR / R25k pm, there's also social housing etc., so you don't really have "poor" people if you can manage to land a job. Issue is more migrants that are looking for a job, but again, haven't had any issue with crime and I've seen one case of someone getting something stolen out of a handbag in the 8 months I've been here, and I take public transit multiple times a day. Cape Town, while I was in uni, I heard of someone getting mugged at least once a week or so, thanks to train station and district 6.
