Not going to happen any time this century, but relaxing the restrictions on immigration or adoption could also effectively achieve "getting the next generation of workers". It is somewhat naïve to imply that reproduction is a strict necessity for getting new workers in developed countries, when thousands of children are dying of malaria and dysentery elsewhere in the world. With the Earth's population way larger than it ever has been before, reproduction at the current rate is not particularly important or desirable. However, lots of parents will usually participate in it as a choice.
