The US dollar was just an example so this discussion is tangential to the point I was trying to make. That said, your argument does not support an increasing value of the dollar - it only says it has increased in value relative to other currencies. But I'm sure you know that inflation has been staggeringly high which means you get less food on the table for a dollar, and salaries have not been keeping up.

Or put in other words, if you were to invest in US dollars instead of shares then you would have seen the value of your portfolio going down, in terms of what it can get you at Costco.
