They had qabil as well and they wasted plenty of time on it.

And..? Are they constantly fighting about X clan and Y clan? Mind you, these are the same people who were nuked Twice by the United States and had an economic crisis not to long ago. Are they using X clan as a scape-goat for their country's demise? NO, they got their shit together and decided they were going to progress as a country rather than fight for feeble things. We don't even need to adopt Japan's culture in order to be successful, all we need to do is gather honest politicians and citizens who are willing to put their foot down for change. We were blessed with everything from our geographic position to our wonderful crops and camels, I don't know how a place like Japan can out-do us.
