Anecdotal but my perception is that clothing has become so extremely low quality, and I assume dirt cheap to produce, that they have less of an incentive to let it go to waste. When I buy socks they get holes after wearing them 7 times, and then they go in the bin too.
Stated another way: you can total up the manufacturing cost of the shirts you destroyed ($50) and distributed evenly among the ones you sold (50/50=$1 each) and just add that to the cost of each shirt you sell when calculating profit. Same result.
What's happening in this case is that they are overproducing because profit margins are high enough that they can overproduce and still be happy with the profit after discarding the extra, in the hope of capturing the stochastic upside of extra sales from never being out of stock.
This might cause various random fast fashion junk items to occasionally go out of stock when they wouldn't have in the past, but it's not like you're going to see long waiting lists or high aftermarket prices. People just won't buy that stuff because there will be lots of alternatives, are they just won't buy anything at all and realize they don't need it.
So yes, in an abstract textbook sense, the price might go up in the sense that you might experience some probability of your desired items selling out when that probability was lowered before. But I don't think anybody in their right mind would argue that's a serious economic detriment.
Maybe there's a case to be made that this is a crude way to address what is essentially an allocation failure. But that alone doesn't mean that we shouldn't try it or that it's bad policy.
but brand dilution
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.
After all, the company could have arguably instead produced fewer product, sold what they have already sold for the same price, paid their workers the same amount of money to do less work, they wouldn't have to pay for the destroyed goods, and wouldn't have had to pay for the wasted input materials...
All in the name of profit FOMO.
the western ordered cheap quality overproduction solution of swamping developing countries with it, where much also ends in a trash heap, means they can continue the exploitive and environmentally destructive mass production.
Smaller local industries would be economically better for the countries, supply more aligned so less waste, and there’d be less of the bad factories in Bangladesh.
The US and I assume Europe have laws against "dumping" - selling a product for below cost - because it drives local competitors out of business. That is exactly what shipping containers full of clothes to Africa does.
This is not only clothing and apparel, also sporting goods and many other items.
This should be forbidden across all industries. Unsold stock should be delivered to non-profits at no cost for further distribution.
If you can't prove that you either sold or transfer to non-profit an item you manufactured then you should be fined for each unaccounted item proportionally to their market price.
Also the first non-profit to build gigalandfills in Africa.
