I live in Muslim majority thats is impoverished. A large part of islam comes in the form of promises for the after life. when i was still question my faith, a line my mom would use to convince and herself out of doubt was that Western countries who are mainly non-Muslim are rich while Majority Muslim are poor therefore we are the victims and thus are in the right.

Leaving out the fact that alot of Muslims countries are rich then most of the world, it falls into the narrative of this all of being an ultimately test. Add that fact that prayer are really a coin. it means most don’t expect prayers to work im the first

but also depends on what you mean by selfish. i would say my cousin is selfish since he spends most of his parents money on himself with no regard for thier financial situation to point where they have to hid the money from him, yet is more regions than your average Muslim
