I’m worried that it takes a certain amount of poverty/desperation in the local workforce to be exploited heinously. For them, an exploitative job is probably the difference between eating a little or not eating at all. Yes, it’s good that they won’t be exploited once the mined diamond industry goes away, but I think they’re still getting the rug pulled out from under them. Their income is replaced with nothing, and in a country with a weak economy, there’s probably very little there to help these people in the interim. It’s a desperate situation, even if it’s for their benefit.
