For niche markets this does happen, and for mass consumer markets the economy of scale comes into play, as the local market is so much smaller than the global market, or the English market, or even the local market of California (I mean, the state of California is economically larger than many countries, and doubly so for the premium market targeted at wealth individuals) that the local adjustments aren't sufficient to outcompete the much larger investment available due to a larger market. But for the larger markets this definitely does happen.
