Via the ever-marvellous Nag on the Lake, we are treated to a rather interesting and thorough comparison of Gross Domestic Product per capita and purchasing power parity of nations richer and poorer than the United States in 1980 (a rather unique instant in time given the 1979 Oil Crisis) versus how they are faring relative to today.
Of course a lot of things occurred over the intervening decades that factor into the changes and reversals, like with the benchmark of Germany of then and now but is nonetheless a revealing look at the geopolitics of economies and invites one to fill in the gaps between these snap-shots.
