No problem.
We'll just import 15 billion young immigrants and lose our quality of life, freedom, and cultural identity rather than fix what's broken.
And when those immigrants get old, we'll just import more.
In the meantime, our living standard, education level will substantially decline and we will forget that it is unbeneficial to breed like rabbits. We won't need 3rd world immigrants---we'll start making our own!!!
And you guys thought we wouldn't be producing anything in the future!?
