The Economist recently had an article about attempts to suppress the used clothes trade in East Africa: Let them weave their own.
The UN estimates that Kenya imported 18,000 tonnes of used clothes just from the UK in 2015, and we are not the only source. That has to stop by 2019 say the East African governments so that "local manufacturing can be boosted" and the buoyant textile industry of the 1960s and 70s (which I remember) can be reinvented.
The article reckons, quoting local people, that such imperious command and control measures won't work as people will need to get their clothes from somewhere – China will be a willing donor, maybe, though at a price.
Time will tell; meanwhile, this would make an excellent global learning case study for those interested in how economics and real people's lives interact.
