Possessing wealth in and of itself is not wrong, however, it can’t be all consuming such that it distracts you from everything else. One of the principal objectives of zakat is to force you to give something you love for the sake of Allah. We must make a regular habit of taking stock of our shortcomings and identifying ways to improve upon them. One is either on a path of increase or decrease in their deen and iman, and as such, one should always strive to improve, because if you stand still, you will inevitably be on a downward trajectory. The nature of the world is that one is never satiated by it and, thus, one has to be content through other means that are not materialistic.
