The turmoil in the Middle East has been instigated in part by fiscal mismanagement. When the money was rolling in with high oil prices, it was assumed, as always, that whatever trend is in motion will remain in motion. Consequently, the government expanded their spending assuming money would continue to flow in. When oil broke, the fiscal mismanagement has been exposed for all to see if they care to look.
Falling oil prices have decimated revenues and trade in the region. Security worries about terrorism, particularly in the US, have led to cuts in airline routes. Then there has also been a long-running diplomatic and trade impasse between Saudi Arabia and its allies on the one hand, and Qatar on the other. Now the good-old-days of easy money and rapid growth has led to concerns about over-capacity, waste, and corruption that nobody cared about when money flowed like oil.
