How can welfare state with high taxes survive in the long run?
I'm thinking of countries with economic and social policies like Germany. So, we can easily observe that in most developed countries, the birth rates are dipping (surprisingly). To my understanding, it is the young who are working (and hence taxed highly) keeping the system a float.
Suppose there is some point in the future where the age pyramid flips, that is old people becomes in majority, then, What type of policies and checks do countries and states such as these in case of such scenarios?
