My argument rests on the fact that the US economy is the world's #2 manufacturing economy, has among the highest median incomes (and median disposable incomes), has one of the most productive economies with one of the highest GDP per capita numbers, does not have a demographic bomb going off (Europe, Japan, China), is capable of being fully self-reliant on energy (which very few nations are), has a boom coming in energy exports via natural gas, continues to have one of the most innovative and dynamic economies, is growing as fast as or faster than competing major economies, owns 45% of all global wealth, has significant spare taxing capacity, US households dramatically reduced their debt to income ratio over the last five years (while most competing economies have seen increases in that ratio), and is the global leader across numerous major industries.

You picked out the one thing that is the easy trump card: the global reserve currency makes it all that much easier for the US.

I must disagree. The US has a shortage of employable workers as evidenced by the current unemployment rate relative to wages; it has a demographic imbalance where too few young people earn enough to support resources drawn by a much larger aging population; and there is no realistic excess taxing capacity for political and economic reasons outside the scope of this reply.
