I find this horrible to parse, though presumably you get the hang of it eventually. I assumed it was missing a zero until I looked up the exchange rate. A grim situation (the wage).

It's indeed a bit delicate for governments to make different rules based on size, but many do, there are lots of rules you don't have to follow until you have 50 employees, etc, in many countries. They don't exactly bulldoze you at 51, but they do incentivize staying under this.
But the size of the gap just sounds just crazy here, "labour laws ... retail workers must earn at least R3,701 per month" compared to "earning as little as R400 ... per month" -- call it a factor 40 between the legal minimum wage, and the going wage which provides these (useful, even essential) services. That's a big gap to bridge!
