Per capita income
Per capita income declines when the price of oil declines (per capita income reportedly fell at one point (1995) to 1/4 of what it was prior to the revolution); Accumulated assets of the Iranian middle class—carpets, gold, apartments—that were acquired in the four-year boom after the 1973 oil price rise and served to cushion the fall in standards of living, have now reportedly "largely been sold off."
