I personally feel that most of the working citizens in America, today only work so they get payed and they have something to look forward to after they have retired from working their whole adult lives. It's nice to be treated every once in a while when you've done something great. It's even a possibility that a good hand full of people might even quit working just because they don't have something to look forward to. Maybe if they got payed more and put it away for a rainy day they might not complain, but there is always a chance.
The answer is c) find religious freedom
For most of the recorded history, or more specifically till around the period of the expansion of the Arabian Empire, it was a relative unknown for most of the the other countries. It is not that the others didn't knew the region, but the region was not of interest of any of the other countries so it was left mostly unexplored. This was due to several reasons:
- The landscape; it was and still is a desert dominated region, so it was dangerous and unattractive for most people.
- The population; there was a very small population which was predominantly nomadic so it was not of great use for the foreign countries.
- Scarcity of resources; Arabia lacked any significant resources that can increase an interest in the region, and the biggest problem of all was the lack of water since the Arabian Peninsula doesn't have a single constant river flow.
