I see where you're coming from, but your conclusion is incorrect. Monotheistic religions, atleast the unfabricated, do not profess the idea that this material world is wholly bad. It professes balance, between the material and the spiritual, and that if you lose balance and become too materialistic (as what we see in today's 'depression' cases) you will fall astray.

I think this idea is very true, and we see that both religious people and non-religious have tipped the balance too far on either side.
