Welfare queens?
The employment rate for Japanese prime-age women exceeds the U.S. rate of labor force participation. The U.S. rate trended down to 74.3 percent in 2016 while the Japanese rate has risen to 76.3 percent. Source: Brookings Institute
This high rate of labor force participation help fuels Japan's economy short term, but long-term it's building into a catastrophe. The more women working full-time jobs, the less the number of kids they have, and on average, that means between one and two (1.4 kids per women total fertility rate), which means their population is in actual decline.
With the average female age 49, almost menopausal, it's not going to get better unless there is a huge social revolution that gets the women ages 20 - 30 out of the fulltime workforce and into serious family growth.
Which ain't happening. It's all trending toward national extinction.
The big techno revolution? Sex robots.
