The collapse of industry, the rise of oil; how did Iran’s economy get caught in a vicious cycle?

According to Energy Press, economist Masoud Nili stated at the 9th Masterbatch and Polymer Compounds Conference: This industry provides the economy with foreign exchange so that imports can be formed for that industry. The industry itself is not the focus of employment, but it creates employment in other economic sectors. Since 2011, our economy has been deindustrialized.
He continued: Over the past 20 years, industry profits have decreased, which has also caused investment in this sector to decrease.
He pointed out the important issue of increasing energy intensity that has occurred in the industry and said: Energy intensity in industry has increased in recent years. In other words, more energy has been consumed in our industry per unit of production. Most of this increase in energy intensity has occurred in large enterprises such as chemicals, petroleum products, base metals, and food, and their share of the industry has also increased, while the share of other industries has decreased.
