In 2006, chief of "Business Week"s Moscow bureau Jason Bush commented on the condition of Russian middle class: "This group has grown from just 8 million in 2000 to 55 million today and now accounts for some 37% of the population, estimates Expert, a market research firm in Moscow. That's giving a lift to the mood in the country. The share of Russians who think life is 'not bad' has risen to 23% from just 7% in 1999, while those who find living conditions 'unacceptable' has dropped to 29% from 53%, according to a recent poll". However, "ot everyone has shared in the prosperity. Far from it. The average Russian earns $330 a month, just 10% of the U.S. average. Only a third of households own a car, and many—particularly the elderly—have been left behind".
