@theFlow By not being there, by having commodities to trade and the means to protect them, or by having skills to fix things, to fix people, or to create things is how you survive during hyperinflation.
@theFlow As to the question of affording children, it's a question of standards of living. You might not be able to afford the best healthcare, but maybe you can get cold medicine still. A feature of life in hyperinflation is that there is no closed system wherein we can observe all the variables. What I do know is that black markets exist, and as things get less and less stable economically, the government will become more and more desperate to maintain power. Do not be there when it breaks.
