alt Hacker NewsIt's absolutely not an absurd set of assumptions. The majority of the demographics you're worried about are beneath the replacement rate. They are going to necessarily reach a point where the youth workforce cannot sustain the outsized elderly population or protect them in a war scenario.
If you do not want to defend Europe's front lines with teenage conscripts and geriatric riflemen, you need a way to bring warm bodies into the fold. Refusing lawful immigration will undermine domestic security, doom the elderly and ruin pension funds for future retirees. No sovereign wealth fund is worth losing your sovereignty over.
Yes, they are an absurd set of assumptions.
I told you what the requirement was. Money. You have simply arbitrarily decided instead it's just people for no reason at all. As though magically people will spawn resources from their finger tips. According to you the richest countries in the world must be the most populous.
Obviously this is idiotic to even a cursory examination.
The next assumption you've made is that birth rate is completely random, a roll of the dice, an unchangeable fact of the universe. The reality is of course it's a result of policy and economics. This can be solved extremely easily.
