You, me, and most of the folks on this board have a pretty high stack of $$. Not rich, but not poor either. Either upper middle class or lower upper class.
We’ve done reasonably intelligent things with that cash: diversified, real estate, etc.
If things tank so bad that we are poor, over 95% of the population will be in way worse shape than we are. Way worse.
We are going to be just fine. No guarantee we’ll live high on the hog, but a good chance we will and if we don’t, it will be because of an event or events much bigger than we had control over and there would have been nothing we could have done anyway.
Let’s say you have $1M saved. You probably have much more. Things tank so your $1M is worth $1K in today’s dollars. Do you think that $3.50 you saved by not buying a perfect bar is going to make any difference at all? If $1M -> $1K then $3.50 -> $0.0035 or a third of a penny. You could have bought three perfect bars and just have spent a single cent.
Or perhaps worrying makes you feel better. In that case worry away!
