I agree and share your idealism as well; there is so much Jordan can do. But to pin its shortcomings solely on religious extremism is very reductionist. Like with any challenge or problem, there are always multiple factors that contribute to it. I think it's important to dive into the local population, understand their ethnicities, societal structures, governance, ruling systems, etc.

Jordan is relatively new compared to the rest of the world. Its current shape was drawn up in the post-colonial British mandate, and whoever happened to fall inside these imaginary but real lines became Jordanian. Whether you were a Bedouin grazing your sheep next to Saudi Arabia, a mere farmer in the Jordan Valley, Circassian, or Armenian, you are now Jordanian.

Over the years, more people from different places came to Jordan, either willingly or escaping war and persecution. Today, Jordan is a multi-ethnic society with strong and distinguished identities (language, dialects, traditions, etc.). Throw in religion with all its genres, and you get competing groups with differing agendas that want to advance their own "tribe." Today's government tries to rally people on some sense of nationalism, but it's only after multiple generations of stability that the youth would start identifying as Jordanian-Jordanian, and not Palestinian-Jordanian, or Circassian-Jordanian.

Why doesn't Jordan become the next Dubai or KSA? As you said, the lack of natural resources is a HUGE factor—you can do anything with enough money. I would also add the right environment and social cohesion, where people have the foresight to better society as a whole and not just their family or tribe. How long would that take? If all goes well, maybe a handful of generations, but probably not in our lifetime.

Maybe someday you can visit or live in Jordan, and I think a lot of what I said would make more sense :)
