What if these people , these small workers start their own brands and directly receive payments in Bitcoins ? What matters is skills , the price will be cheaper for the person buying it and these people will even make more.
People buy famous brands for two reasons - they trust in brand's quality, because they can't verify the quality on their own, or they buy a brand because it's a status symbol on their own. There are already countless smaller brands and no-named manufacturers, but I'm pretty sure that they pay even less than these big brands, which is why poor people will keep sticking to their jobs there.
Bitcoin solves absolutely nothing here, since there's no monetary problem here, and if a company tried to only accept Bitcoin, they would sink in their first month - that's how low the adoption is right now.
