Russia overtaking Japan would be a REALLY tall order by 2030, even on PPP measures. It requires Russia grow an average 3% points more than Japan until 2030.
Not absolutely impossible, but extremely unlikely, short of Japan’s debt bubble unwinding in catastrophic fashion.
Brazil, Indonesia – Virtually impossible
Turkey – This is entering “WTF are they smoking” territory. Would require the average Turk become as rich as the average American.
Egypt – Implies Egyptian per capita incomes equalizing with those of the world’s most technologically complex economy.
