If you have skills, you can always earn more.
Mind you, the devaluation is a bit of a problem. We want to be able to save long-term, including retirement.
The best option right now is a stock portfolio, very few people keep cash around.
But the current "cost of living" of crisis is not about that, it's about current earnings not going up as fast as current expenses.
But then you're just on the wrong side of the equation. If you're spending more someone else is earning more because the money doesn't go away ya know?
