does the US have enough gold to cover the money out there that it owes?
Possibly, but it probably would need to be revalued to about $30k/oz.
Therefore, I don't expect change, and do expect the debasement and debt to continue, expect leftist cities and states like Chicago and Illinois to get regularly bailed out, and expect absurd amounts of govt money to continue to be spent on neo-marxist social-engineering - like waves of illegal immigrants, for example.
Yes, in a devaluation that is actual default, by decreeing the price that the government buys and sells gold for maybe $20,000 ounce.Depression would follow and if we still had an effective military the country would ride that out and emerge strong again.
