Not always a win. There have been a few reports that sending large numbers of clothing donations to areas that don't specifically need them has the result of harming local industry that would otherwise be able to produce and sell clothes.
The appearal industry is among the most exploitive in the world. It's good to kill it before it springs up. Bangladesh is not anyone's example of a model country.

I don't care. If you over produce then you made a bad economic decision, tough luck. Destroying goods for accounting reasons is an abhorrent policy driven by greed.
