Well, you should go there and see for yourself how much better it is. I have done that, and I can tell you without any hesitation that I would rather be poor in Tokyo than in San Francisco or any other major city in the US. You can get across Tokyo on a train for the equivalent of a few dollars, there is universal health care, rent and home prices are lower, and Tokyo is more cosmopolitan. Unless you are looking for software engineering jobs, Tokyo is a better place to live. And on top of all of that, the population of the Tokyo metropolitan area is almost as large as the entire population of California.
