Insolvent you say? The US owns 45% of all global wealth (per Allianz&#x27;s global wealth studies, it was ~50% pre great recession, fell to about ~39% in 2010 as the US suffered heavy asset declines, and has rebounded back to around ~45% with the recovery in the US economy, that gap is mostly the arrival of China&#x27;s wealth). The US is massively solvent in fact. Furthering this point, the US is now growing as fast as China in real terms (given pretty much every credible study indicates China is at least lying about half of their growth); the US is also gaining substantially against most of Europe, as its economy continues to grow faster than Europe even with a stronger dollar. South America and most emerging markets have been thrown into near-depression status, due to the stronger dollar. The US economy is likely to enjoy a very nice 10 or 20 year run in fact.<p>Russia&#x27;s economy is now - as of the latest 2015 numbers - 1&#x2F;12th the size of the US economy. It no longer matters as a global economic <i>power</i> (it still matters as a global commodity player). Its economy is smaller than Canada&#x27;s now.<p>China will continue to use greenbacks because they will never have any other choice, the same as they&#x27;ll continue using Euros. The US is back to being China&#x27;s biggest trade customer (with the dollar having gained so much value): that trade is mostly done in dollars and that will continue.
