Jesus doesn't say wealth is a bad thing. Some of His best friends were wealthy. But if you value things more than people - then there's trouble.
It is my firm belief that the most important thing anyone can know for certain is that life is eternal. It's when we don't, when we doubt, then we value all this junk more than each other. We want all these things, bigger things, better things, because we really don't believe we'll ever have anything but these things.

We crawl over dead people and don't notice they are even there under our feet to get 20% off at Walmart.
We think death is a bad thing. We do anything at all to live just a bit longer. Starving a stranger to death because we have to have more and better to live longer, we deny our own part in the life of our brothers and sisters.
And if we do care, the problem seems insurmountable. And we let go of doing because we don't believe in life, or prayer, or God, or anything at all but the stuff we can grasp. Which is why despair is considered a sin. It is lack of faith.
Mother Teresa said something like, "Don't worry about helping everyone, just start with the person closest to you."
