I think that kind of misses the point. Sure, of course plenty of atheists find meaning in life and social groups to join.

Point being, in a religious environment you don't have to have skill - the meaning in life and social groups are automatic and baked in. That's not the case for atheists so it's easier to get "left behind" if you happen to be "unskilled", as you put it.

I agree about skill. It’s just easier with religious groups.
