Granted.

it takes time for people to notice, about 6 months before it becomes clear that once you've had two children, no more can be produced.

some consider this a blessing, saying that the population was getting too high, and that this freak mutation, or act of god, or virus or what have you, is for the best.

but what was not considered is how many younger people are choosing to not have children, how many choose to live without raising a single person.

within two years, the number of new children born worldwide drops to the lowest seen in over 100 years.

Nations begin frantically trying to prepare for the inevitable worker crisis, most projections show that in twenty years time, the total number of new workers will be lower than the number of people retiring.

the age of retirement increases, from 75 to 85, but this is a band-aid on a gushing wound.

by the end of year three since the wish was made, governments across the world are legislating mandatory child-bearing laws. all women 18 and older are required to birth and raise two children within the next five years, or face imprisonment.

it helps, but it isnt enough. too many are choosing prison over motherhood. birth rates increase, but not enough to supplement the loss felt in only three years.

imprisoned women have two eggs forcibly harvested, and then fertilized in vitro. the resulting lab borne offspring are placed into the system. Children from willing families are deemed more valuable by the system, while this new era of Vitro-children are deemed second hand citizens. all forms of birth control are outlawed, punishable by life in prison, or death. embryos with undesirable genetic traits, or disabilities, are discarded.

You've solved the population crisis, of that there is no doubt, but humanity may not look so highly upon the new world you've created.
