You don’t think the population would turn around if they young ones wouldn’t have the elderly to support?
Not in a significant way.
It falls mostly to the middle aged,out of their prime kid making years, to take care of the elderly that can’t care for themselves.
The problem in Japan is that too many young people in their prime don’t want children. No matter their personal circumstances. Too many Japanese in their 20’s and early 30’s want to spend their time and money on travel,luxury goods,high end restaurants,concerts and electronic gadgets. Or living in some sub-culture rather than raising families.
Too many Japanese in the 20-35 age bracket, not unlike their Western counterparts, want to live in an extended adolescence but with more cash.The real problem does not seem to be time or money but rather the desire to have children and live in a family unit with adult responsibilities.
