2 has some options.
Increase the number of (young) immigrants. Increase the birthrate (has anywhere managed this?).
They talk abiut the squeeze, if Birthrates increase too suddenly - workers would both have to pay for the elderly and the kids.
If one generation has a fertility rate of 1 child per woman, the next must have 4 children per woman to undo the demographic change.
The people in the “corrective” generation must support their own two elderly parents plus four of their own children. It becomes practically impossible.
The country and the individual has the same problem. But it also goes a generation further.
There was a link on HN recently which I can’t find. It discussed how we are in an unusual time, where kids can often meet their great grandparents. Previously people died younger, so couldn’t. Now people are having kids at an age where it will be unlikely for them to meet their great grandchildren.
I'm not sure that's true - people died younger, sure, but they also had kids much earlier. Even assuming 18 for first child(and it often was earlier than 18), you'd be a great grandparent at the age of 54 - and people have commonly lived that long even in antiquity.
The average lifespans was only 40-something until the 1850-1950 range.
I’m sure plenty lived longer, but the average was terrible.
"While the most common age of death in adulthood among modern hunter-gatherers (often taken as a guide to the likely most favourable Paleolithic demographic experience) is estimated to average 72 years,[169] the number dying at that age is dwarfed by those (over a fifth of all infants) dying in the first year of life, and only around a quarter usually survive to the higher age."
Etc.
The US since then only provides Israel with military aid (most of which is only allowed to be spent buying US-made goods). It’s more of a subsidy for the US military-industrial complex.
Also despite the military aid Israel still spends a much greater share of GDP on its military than most or all other developed countries (so the US isn't subsidising Israel’s unusually high birth rate).
That's a funny way to twist it. US is providing aid to Israel. Billions a year.
US also provides indirect aid, through protection or aid to neighbouring countries (e.g Jordan and Egypt) as bribes so they play nice with Israel.
And who knows, with the way the Iran thing is panning out, you might be paying a lot more if US decides to bomb Iran on Israel's request
If the US starts sending proportional military aid to South Korea (fertility rate of 0.75 vs Israel's 2.83) it will not "fix it".
The US provides and provided a ton of assistance to Israel but there’s a tendency online for people (probably mostly Americans?) to assign credit to literally everything that happens in Israel to US aid.
Israel exists outside of US-Israel politics and not everything (like birthrates) that happens there is because of the US. The US also supported/aided a lot of other countries that didn’t experience the same economic/industrial/technological development that Israel has in the last 30-40 years - some of it really is because of Israelis’ efforts and not just because of Americans’.
That’s one hell of a disclaimer on the statement.
Increase the number of (young female) immigrants
To me it seems rather obvious: you need both the will and the means to raise 3+ children.
In fact, they may majority be of subsistence in which case the entire dollar value of all of their stuff is simply the land.
The catch-22 is that the people you presumably want to be having more children— educated working professionals— have some of the highest social standards for child rearing.
