Materialism leads to 3 different kinds of suffering:
First when we see what other people have and we don’t, we suffer.
Then when we try to get it and cannot, we suffer.
At last, when we come to know that we won’t be able to get it , we suffer.
The real problem is our expectations, not the material things themselves.
Materialism is the attachment; the idea that happiness is found outside.
