KUWAIT IS A RENTIER state that profits from most of its income from its oil trade goods and from foreign investments. Oil revenues have been used to sustain an extensive infrastructure and industrial development, as well as a welfare system not based on taxation. Some of the benefits allocated by the state to citizens are low-interest loans, subsidies and special prices, social allowances, and gifts for marriage dowries. More than 90 percent of Kuwaiti citizens are employed by the public sector, which has led to an increasingly bureaucratic organization of society.
