I haven't done a good job of making that clear at all, and I apologize. There are surely a lot of people trying to reach FIRE goals and if that were to be a meaningful 15% of the population, how would we be affected as a society?
One thing that's interesting in all this is that a common FIRE tactic is to live very frugally your whole lives to achieve and then maintain FIRE. If a meaningful percentage of Americans stopped spending as much money, the economy would feel it at a certain point.
These are the kinds of society-level thoughts I have been aiming to discuss. FIRE makes for some interesting futurism if it becomes the dominant American household financial strategy.
