Also, free democracies tend to destroy themselves once the electorate realizes that they can vote themselves money. I would say that our electorate has realized that. And, we have leaders who are willing to leverage that for their temporary gain, and they are calling for "increased democracy," by which they actually mean increased socialism, because they know the electorate will vote themselves other people's money. And, the checks of Federalism have diminished sufficiently that the electorate might succeed (and we have leaders who want to destroy the checks and balance that Federalism provides...eliminate the un-democratic Electoral College!...stack SCOTUS...eliminate the undemocratic filibuster, and next the undemocratic Senate).
We can discuss when the dollar will collapse, but there is no reasonable discussion that it will not. It obviously will. So, I wouldn't get all high and mighty disparaging people who say what is obviously true.
And, if you are one of those people who thinks the US government is building a ponzi scheme of sorts by spending more than it takes in year after year after year (borrowing from future generations to buy caviar now...taking out credit cards to pay the mortgage), you might think that the collapse will come sooner rather than later, and you might want to have some wealth held in a non-USD form.
Notably, we can't predict when it will happen. I actually think the people running the Fed are pretty smart, and I think they are highly motivated to keep the ponzi scheme running as long as they can so it collapses on their children's watch, not theirs...and I think they will dream up crazier and crazier ways to kick the can down the road...until they can't. It will happen fast when it happens. And very smart people will not have seen it coming...while people with common sense will have recognized that whenever it happens, it was always inevitable.
