>It costs considerably less for the state to support a child than an elderly person. I would like to see the numbers on this... In today's world, a young person is supported for at least 20 years, sometimes more. Life expectancy in Japan is 84.6 yr (the minimum Japanese retirement age is 61 yr, set to increase to 65), so older people are supported for at most 23.6 yr. Further, older people are most often supported by their own investments and assets, which can be invested in any productive location, rather than by the earnings of a couple of related adults.
