USSR, UK, Europe, Japan, China etc all that were hurt during WW II and every other third world nation out there had a lot of very good years after the war in 1945. In 1945 they were at the bottom of the pit financially. Living standards at their lowest.
Thanks to the Federal Reserve and other global governmental organizations, that “made” the USA consumer and taxpayer help them fight the wars and rebuilt their destroyed nations after 1945.
Once the US real estate market crashed in 2008, the other nations followed us because of that. The USA living standards are in decline since 1975.
The others, only since 2008. This is why I think the global powers are focusing on helping the USA FIRST, with the assumption that if the Americans do good, so will the others later on.
