It is hard if the population is shrinking because the two shrinking parts of the population, children & working adults, are essential for GDP and tax revenue; while the growing numbers of retired seniors just put even more strain on the system. There’s a threshold when taxes get too overwhelming.

You’re still down to some major choices:

* End immigration and end public benefits like healthcare

* Keep immigration and keep healthcare for now. Then pray that someone finds a solution someday to a shrinking population because immigration will only slow it down.

* Drastically increase taxes. This isn’t really a viable long term solution because in most places that have a lot of socialized benefits the taxes are already very high.
