Toms is a shoe and clothing companies that uses 'buy one give one' business model, meaning for each pairs of shoes sold it will donate another pair of shoes to impoverished people. The countries to which the free shoes are sent have included Argentina, Ethiopia, Guatemala, Haiti, Rwanda, South Africa, and the United States. It won some awards, mostly related to its creative business model and 'charity' spirit.
This Adam Ruins Everything video Why "Buy One, Give One" Companies Don't Help Anyone 'debunks' this business model (at least its claim to charity and philanthropy) by saying that firstly the shoes aren't that needed, and secondly all the imported free shoes are hurting local businesses that produces shoes.
Are there specific data or information that supports this debunking?
