immigrant in 3rd world countries either due to poverty or religious beliefs have more kids then they can afford
result is high unemployment and migration towards countries that have low birth rates
resulting in a flood from low economic zones with out of whack birth rates to areas with small birth rates
japan recently decided not to import immigrants to compensate for lack of children
they decide to robotize their eleder care
N HOT WATER: A nursing home resident enjoys a visit with her robot bathtub. � Borrowing an idea from the auto industry, Japanese nursing homes have begun experimenting with using robots to help care for the elderly. At one nursing home run by Matsushita Electric, a package of sensors is placed inside a teddy bear. From time to time, the bear asks its human companion a question. Then, judging by the response time, it decides whether a nursing assistant should be called. One of the most labor-intensive nursing home tasks is bathing frail residents. For this job, Sanyo Electric has introduced what is essentially a robot bathtub. Costing about $50,000, it closes around a patient who is seated in a wheelchair. The wash and rinse cycles operate automatically. A nurse's aide takes care of washing hair and toweling the resident off. Japan's need for elder-care robots is partially driven by a falloff in its national birthrate, which has left the country with too few young to care for the old. The Japan Robot Association expects the demand for elder-care robots to help the personal-robot industry grow to $40 billion by 2025. http://odiumcorp.blogster.com/robots_help_japan_care_for.html
