ok... guess it depends on ones definition of "worry" and "safety".
For instance, I do not worry that the US financial system is a house of cards... as you pointed out, we have most the others by the balls with US$ as reserve currency.
but, i do not discount the fact that whether government(s) like it or not, shit happens. ;-)))
as you pointed out in other threads where you reference Rome, Egyptians, etc.... where are they now?
I feel safe knowing what I know about markets and am not afraid to keep my funds in US, so I feel safe like you do.
All things considered, I agree with you when you spoke about life first and living with LL in a tent.... life would just be one long camping trip and I still have my mule!
