well I hate to bring up enviroweenies, but wasn't that the plan? For us 'educated classes' to lower birth rates so that our countries didn't outlive their resources? So we could build less but more sophisticated schools? So we could grow our industries sustainably? So we could buy time for science to solve the pollution issues as we busily worked to preserve pristine environments for our descendants?
Ah, but now the collective lament is the 'educated class' countries suddenly don't have enough population, and so now these same advocates change course and demand tolerance for mass invasion by the uneducated and uncaring into those same environments and systems of government so carefully preserved at such an enormous cost.
