Well, it's only a very, very recent problem in Japan. They had stagnation for decades. Little to no change in wages, little to no change in prices. In 2011, I was making something like 33,000 USD per year there and living very comfortably with ample savings and what the Japanese considered to be a large apartment. It's a pretty affordable country, aside from travel. Or if you want to live in a fancy place in a desirable big city neighborhood.

(And yes, I have been to Japan since then and know that things have changed somewhat. It's still cheap compared to the US. Food is so cheap, it's amazing what you can get.)
