Summing up the discussions, it seems to me that US is the capital lending source for the world. Every country loans, saves and invests in US dollars to improve their economy. Previously this role was played by Gold but gold source is limited while US can ensure(theoretically) unlimited supply of dollars. So, in effect, all the growth that we saw from 1971 was due to this switch from Gold. This arrangement works well for everyone. The other issue about US sanctions will push the rest of the world towards searching for an alternative, is not true.The reality is, the rest of the world adapts and tries to compromise with US. May be it is first mover or luck or strength of US economy, but this role played by US is not likely to be replicated or substituted. But, interestingly, this role of US dollar is very beneficial for capital or investments in US. And by the same corollary, is very bad for US labor, since they are competing not just against the other countries, but against US dollar. May be this is also the reason for the unrest and social protests?
