There really isn't much of a choice, and even then it's not a long term solution. From the article:
"Morland talks of the trilemma facing ageing nations, whereby you can have two of the three: ethnic continuity, a thriving economy or a comfortable lifestyle without the huge stress of mixing child-raising and a modern economy. Israel has sacrificed the latter, Japan has chosen to take the economic hit, while Britain’s leaders have given up its ethnic continuity. But that, alas, was a short-term solution, since young immigrants don’t magically avoid the fate of Father Time any more than the rest of us do."
