I just wonder how much are the proceeds, if you pay the rent for the shop, and a wage for the workers. "Profits" go to charity but, you know, Profit is what remain after all Costs have been deducted from Revenues.
If the workers work for free, then it's charity. If the workers don't work for free, and the space is rented, then it's business with a nice label. And I have nothing against business, with any label.
Intrigued by this thread, I begun searching "thrift shops" in Rome (or Italy) where I never heard of them. The translation I found for this shop is "mercatino dell'usato", "flea market". The concept of "charity" is totally lost, and, in fact, is totally extraneous to the business I do believe. I think it is a deep cultural difference. There's no much "ethics" talk in Italy, thank goodness. For instance I've never seen an Italian photographic forum with an "ethic" section

.
Even with a different label, I don't remember seeing more than two of those mercatini, and one was devoted to furniture only.
I searched on the internet for flea markets in the places of Rome where I often happen to be and I found three of which I didn't know the existence. I visited one of them near my place and it was quite interesting! Thanks APUG as you made me discover something that I really never stumbled upon before now, I knew its existence but never got interested in them.
Certain things were expensive, certain other were probably bargains if you needed them or liked them.
Just like they don't feel guilty to ask "too much" for certain items, so you I wouldn't feel "guilty" when I think (maybe mistakenly) I found something at a bargain price. It's the game.
Evaluating old objects is difficult, and many antiquaries do just that, go round those flea markets and look for "bargains", and the profit is the remuneration for their knowledge and skill, which is honest. On the other hand finding an use for things that seem ready for the landfill is hard and I suppose the shopkeeper himself wonders sometimes what the hell are you going to do with a book written 50 years ago about film development
The shopkeeper just cares about profit (or charity if he donates his wage) and if any item goes out the door at more than it came in, he's in profit.
Space is limited, and things have to go to make place for new stuff. Provided the things go out at a profit, any shopkeeper is happy. Provided clients go in an get out satisfied, any shopkeeper is happy. Buy things, and everybody is happy. No need for self-flogging
