It could contribute to it but seems to miss... idk.. the whole history of the Middle East post Western involvement. The patterns we see today in the Middle East go back to around 1900 or so with attempts of imperialists to hit them, divide them, turn them into indentured servants, and take their resources. Combine that with religious, ethnic, power-related, and financial aspects over decades to get a huge mess. So, I'd be looking at money, power, religion, and typical politics as a start.
Looking at that, I see the same trends that relate to violent regime change and terrorism over there that I always see. It usually involves a Western power (esp U.S.) covertly screwing with a country to cause a regime change or battles between them + eastern country (esp Russia) for influence/resources. The radical ideology and funding put in by Saudi Arabia comes into play. The damage and power vacuums from an invasion in Iraq and Afghanistan fuels it, literally with fuel & weapons. ;) Arab Spring and aftermath of that may have been the final straw setting things in motion.
All in all, looks more like Western imperialism, local dictatorships, and religious sect (esp Saudi-promoted) combining to create a disaster that leads to many innocents being beaten, raped, tortured, and murdered over there with a few in the West, too. Same stuff, same area, different country and year.
And, unlike international media, most of the Western media is consistently avoiding the U.S. imperialism and Saudi Arabia angles. Just like they did for Iraq. Just like for 9/11. The problem isn't income inequality: it's countries sabotaging other countries with corrupt ideology, covert actions, and overt war. The result is what CIA types call "blowback." We call it tragedy but they won't let dots be easily connected.
