"If we are obsessed with made in Italy, made in France, the negative side is that everything gets pared down to essentials," he told Reuters. "There comes a point where this slavish respect for 'made in Italy' cannot hold unless the product becomes extremely expensive." (source) I'd like to know what "unless" means here. As far as I know, unless means "if... not". But I don't think "unless" makes sense in the context. If the product becomes extremely expensive, the slavish respect cannot hold. If the product does not become extremely expensive, the slavish respect cannot hold.
