South Korea has an even bigger problem. Look at their male to female ratios in their population pyramid. They’ve obviously been doing sex selective abortions just like China and they now have fewer women than men in every age category until 50+ when women enter menopause.
Even if they fixed their stupid economic policies, it won’t solve the problem of feminine scarcity.
Which is truly a shame because the Korean female is (one of) God’s gifts to mankind.
