Chinese parents will now be permitted to have two kids.
It has been estimated that since the 1970s approximately 163 million girls have not been born due to sex selective abortions. In other words, couples waited until an ultrasound could determine the sex of the fetus and aborted because the fetus was female, resulting in 163 million girls not being born over the last 30 years.
China's 4:2:1 problem is ours, too, just with a different name: A glut of people are growing old and there are fewer of us to pay for their care, while also having to save for our own retirement. At the personal level, there are more of us without siblings shouldering the costs of care for aging parents.
