I worked and danced in Japan... same local first mentality exists there as everwhere.
Bottom line: open system, recruit the best, allow everyone to compete will create the world's best schools and companies. We can only benefit.
I would think that for younger dancers, starting out careers, we need to suport a regional/ national system. However, for performance age dancers, globalized attitudes, mixed cultures, are true to the best qualities of our country.
