What you are describing is when things are now priced in sats, and the prices of everything begin to only go down.
So no, I will STILL get richer over time even if they DO become fiscally responsible. 😆

That doesn't seem to align with current reality. A lot of the value in Bitcoin right now would probably flee if this happened soon. At the very least it would happen so slowly as to be irrelevant as far as getting rich from being early goes. Bitcoin seems to perform best during times of fear and irresponsibility. At least as far as I can tell.
But long term I agree. Fiat will always fail eventually. This was meant to be a joke.
