Countries with less oil to sell do not have the same options.

In Syria, where oil production is drying up, prices have also risen sharply. Although it has begun to liberalize its rigid socialist economy, the government has repeatedly put off plans to eliminate the subsidies that keep prices artificially low for its citizens, fearing domestic reprisals.

Even so, the inflation of the past few months has taken a toll on all but the rich.

Thou al-Fakar Hammad, an employee in the contracts office of the Syrian state oil company, has a law degree and earns just less than 15,000 Syrian pounds, or $293, a month, twice the average national wage. His salary was once more than adequate, and until recently he sent half of it to his parents.

But rising prices have changed all that, he said. Now he has taken a second job teaching Arabic on weekends to help support his wife and young child. Unable to buy a car, he takes public buses from his two-room apartment just outside Damascus to work. He can afford the better quality diapers for his son to wear only at night and resorts to cheaper ones during the day. He cannot send anything to his parents.

“I have to live day to day,” he said. “I can’t budget for everything because, should my child get sick, I’d spend a lot of what I earn on medication for him.”

At the same time, a new class of entrepreneurs, most of them with links to the government, has built gaudy mansions and helped transform Damascus, the Syrian capital, with glamorous new restaurants and cafes. That has helped fuel a perception of corruption and unfairness, analysts say. On Wednesday the state-owned newspaper Al Thawra published a poll that found that 450 of 452 Syrians believed that their state institutions were riddled with corruption.

“Many people believe that most of the government’s economic policies are adopted to suit the interests of the newly emerging Syrian aristocracy, while disregarding the interests of the poor and lower middle class,” said Marwan al-Kabalan, a political science professor at Damascus University.

The same attitudes are visible in Jordan. Even before the subsidies on fuel were removed this month, inflation had badly eroded the average family’s earning power over the past five years, said Mr. Tawil, the former economic minister. Although the official inflation rate for 2007 was 5.4 percent, government studies have shown that middle-income families are spending far more on food and consuming less, he added. Last year a survey by the Economist Intelligence Unit found that Amman was the most expensive Arab capital in cost of living.
