Saudi Arabia is running out of money. The cash crisis is so terrible that the Saudi government just raised the price of gasoline by 50%. Gas used to cost a mere 16 cents a liter in Saudi Arabia, one of the cheapest prices in the world. Many Saudis drive large SUVs and have no concept of saving gas.
    The gas rising is just the beginning. Water and electricity prices are also going up, and the government is scaling back spending on roads, buildings and other basic facilities.
     [6]About 75% of the Saudi government’s budget comes from oil. The price of oil has crashed from over $100 a barrel last year to around $36 currently. Most experts don’t expect a rebound anytime soon.
    The Saudi government used its vast oil wealth to provide generous benefits to its citizens. The Saudi king spent even more in an effort to reduce any discontent in the country. [7]But now, Saudi Arabia may have to start taxing its people. The International Monetary Fund recently predicted that Saudi Arabia could run out of cash in five years or less if oil stays below $50 a barrel. It predicts Saudi Arabia may even have to start collecting an income tax or sales tax.
