Chang Ming-cheng observes that too rapid a growth in the elderly population is very disadvantageous for society. It not only calls for staggering health care expenditure, but will also cause overall production capacity to shrink. A society with too many old people and not enough young people will also suffer the pressure of an excessive burden of care.
張明正指出，老年人口增加太快對社會非常不利，不僅醫療支出驚人，總體生產力也會萎縮，老年人多、年輕人少也會帶來扶養負擔過重的壓力。
