The world is in a corrupted state.
Ever since the irruption of the fallen in the antediluvian era and all of the abominations they wrought in Eden until the flood.
Those corruptions stuck around. If the Book of Enoch is to be believed (I believe it personally) then even civilization itself is a gift from the fallen angels. The question isn't what is wrong with the world as it is now. The question is, what isn't?
Satan is the Prince of this world. His world naturally reflects his character.
John 14:30
Hereafter I will not talk much with you: for the prince of this world cometh, and hath nothing in me.This world then, by association, has nothing in him either.
Prince here means ruler and is used in the same way as prince or ruler of Persia is used in Daniel and such.
Ephesians 2:2
Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:The world is in conflict with the righteousness of God. It just takes one glance at the world around you to figure that one out.
Christianity is an ascetic path in truth. It's not necessarily as extreme as some ascetic traditions, but it's definitely not on the materialistic side of the spectrum.
