Due to the 1973 spike in oil prices, the economy of Iran was flooded with foreign currency, which caused inflation. By 1974, the economy of Iran was experiencing double digit inflation, and despite many large projects to modernize the country, corruption was rampant and caused large amounts of waste. By 1975 and 1976, an economic recession led to increased unemployment, especially among millions of youth who had migrated to the cities of Iran looking for construction jobs during the boom years of the early 1970s.
