This is similar to the concern some have that as the birth rate becomes lower and lower, the new generation--which will have few relatives--will lack an emotional support network while growing up, so that the value system of the whole society changes.
就像有人擔心愈來愈低的生育率，使親人為數極少的新一代，成長過程缺乏情感維繫，整個社會價值觀可能都會改變。
