one would think in free market US economy you will have tons if brands to choose for each budget but the article imply opposite, is it really truth there it's unregulated monopoly? can't you buy cheap glasses in supermarket for few dollars or some event brands for let's say 50-200$ online? looks odd from Europe of course luxurious brands cost more, bit who is forcing people to buy luxurious fashion brands? that doesn't sound like monopoly to me
