Fair would also be to impose a maximum fertility rate. When the fertility rate is off the charts for the developing countries, unfair is the per capita quota.
If the goal is for humanity to survive on this planet, then clearly an exponential growth in population isn't sustainable. More fair would be to have quotas per square meter actually.
Sure let's have quotas per sq meter of arable land adjusted for number of crops you can grow in a year? Or better still on yield of the soil. Makes more sense than a straight per sq m quota.
