What influences economic growth?
Saudi Arabia is located on many oil fields and right near the Persian Gulf. They are one of the biggest exporters of oil in the world. Saudi Arabia has to export oil in order to trade oil for water because of the lack of water in the Middle East.
Israel has one of the highest standards of living in the Middle East. Israels economy is so strong because they invest in human capitals. Their biggest export is high tech equipment. Israel is not located near or on any oil fields.
Iran is also located on a lot of oil fields. Just like the other countries in the Middle East Iran has a lack of water. They all have to get their water imported. Iran's government does not invest in human capitals. The girls in Iran are not allowed to go to school. Therefore their literacy rate is not very high and there standard of living is very low.
