The problem is they don't.
And they never will.
Possessions and pleasure serve a purpose in life , but are not and cannot ever be the sole purpose of life. The irony of possessions is this: you start off possessing them, but they end up possessing you and no matter how much you love them, they do not and cannot return your love. Pleasure, though quixotically addictive and fun, tends to fade rather quickly. The void left behind immediately demands newer and newer pleasures until the idea of pleasure recoils back upon itself, becomes utterly perverted, and is saturated with sadism.
What is left after the possessions turn cold and the pleasures run black? In all honesty, not much. Nothing, in fact. This point marks the border of nihilism, the vast poisonous belief desert of nothingness which inevitably leads to despair. What is despair? Amnesia of meaning. Abandonment of hope. Rejection of faith. Past societies had built-in safety mechanisms to combat such existential crises, but modern societies have contempuously cast these aside thinking, rather foolishly, that the fight against despair is one they would never have to fight and, in the unforeseen event that they would, that materialism and pleasure would provide them with the weapons needed to win the battle.
The problem is, they haven't.
And they never will.
This why the rediscovery of faith and hope are crucial. They are the only things that can, not only save us, but also give us lives that are worth living. Even if we are defeated, we go down swinging or, at the very least we go down smiling, which is far more noble and human than allowing darkness to corrode us and simply cratering in on ourselves and existentially imploding.
Faith is a deep sense, seemingly bottomless, that absolutes exist despite so-called evidence to the contrary. And hope is the undying belief that these absolutes will ultimately triumph - even if we fail individually or en masse in our own short lives - regardless of how bleak and meaningless the present might appear. Faith and hope. Both are crucial and both are needed, perhaps now more than ever.
