Pre covid immigration ran at about 140 000 a year. That's the bare minimum to keep the economy ticking over. So over 5 years that's 700 thousand people. So I ask you again, where are you going to get all these people from? And that's 5 years. Project that to 10 and you have 1.4 million.
No I don't have a solution. I'm not so simple minded to say stupid shit like, 'let's be choosy', when there aren't any real alternatives. Nor do I have the solution to a rapidly aging workforce, a shrinking tax base, decreased fertility and an economy based on perpetual (nee Ponzi scheme) growth.
These are massive challenges as I've already said that are multi-faceted and extremely complex.
However if I were to have a crack at it I would think the number one reason for a negative fertility rate would be the cost of housing and living. People won't elect to have children if they can't afford a house and can't afford to raise those children. (Or will only have one child.)
So that means a massive, almost post WW2 level investment in housing. Where's the money going to come from you'd ask me next. Well champ you tell me? I'd tax billionaires, increase royalties on resources and raise taxes across the board, remove negative gearing for housing (phase it out), ban or severely restrict investment on residential properties, and get rid of the capital gains discount (phased out over time).
You know, engage in a fair bit of wealth redistribution. (All of which I've said before if you'd pay attention.)
Sort out affordable housing as a very first step and then go from there.
I know you're going to scream SOCIALISM at me and that's fine but unless you have a better solution then keep your insults to yourself and put forward your solutions.
I can wait.
