Only the dumb' sucker for Nationalist propaganda, it's like a generic form of nepotism- which is all good until you have a free market place which the internet is creating.
A marketing sticker only adds to the end cost of a product period.
- what you need is the best functioning, quality made product available at the most competitive price.
Focus on those will things and the product will market itself. Technology will slow down and designs will become more uniformed over time- material type and production standards will determine the long term success of a product.
