According to, Japan's unemployment rate has been no higher than 6% over the last 32 years (1980-2012).It's currently at 4.5%[1]
Compare that to the US, who's unemployment rate has been at worst 10% over the last 32 years (1980-2012). It's currently at 8.5%[2]
Why does this supersede most other stats? Because we simply need to keep people busy "doing things", otherwise (as you're seeing in the US) riots/protests break out, crime goes up (crime is largely a result of poverty), and people don't have the means to keep themselves healthy. What more do you need from a society? I understand people will say "but we need growth". I ask why? What is the end result of growth that makes societies "better"?
