You mention being the Sandwich Generation upon which the elders above you rely.
Just curious, do you know what the birth rates are like in Indonesia?
In a lot of the world they are down. Replacement rate is 2.3 per man/woman.
Two for each person, and then the .3 is supposed to make up for negative things that may happen in some percentage.
In the West the govt's have this social system that's supposed to provide for the elderly in their retirement(it's supplemental rather than anyone actually being able to live off it) and people pay into it every week they work.
But it's a Ponzi scheme, and that money doesn't get set aside for you in a saving account. We have more elderly than children or teens, and so there has been talk about raising the taxes to make up for the deficit. The elders are overwhelmingly in favor of doing this, supposedly. I don't know this for sure, but it's what I have heard.

Meanwhile the cost of homes, rent, food, vehicles, utilities is much higher than it has ever been, and the wage growth vs. the inflation/cost increase is not equal.
Most feel that the elders had a much better economy with a lot more living wage jobs available vs. today.
But I can't help but notice that there's sort of that same dynamic at play. Where the elders are relying on the younger people.
This is why I was curious about the birth rates in Indonesia.
