There's a lot of conflict over this, is it wrong to desire money? Can I make a lot of money and still be a good person? There's even been a kind of spiritualization of money recently where you're supposed to get more of it the more in alignment with God or your Higher Self that you are. It's a rather emotionally charged subject, one with a lot of guilt surrounding it, and it's something that really needs to be looked at more deeply.
Money has become so integrated into our lives that it seems like it's a normal part of the human experience. It seems like our society needs money to run properly, yet money, at least as we understand it today, is a rather recent invention. It's not really an essential part of our experience, and there's perfectly healthy ways of living that don't involve money at all.
There's this idea that money is simply energy, and while that's true, the energy we're talking about here is really your belief in its value. Without that belief, money would mostly just be paper and numbers in computers. Understand that the energy of money comes from humanity collectively giving it their energy.
So who controls this energy that is money? In a fair system, everyone would, but that's not how it works, is it? In reality, it's just a tiny portion of the population that controls the vast majority of the money, and because most people's lives are so money-focused, this allows a wealthy elite to control billions of people's lives through money. So money has become a tool for control, which is why so many people view money itself as something evil. Of course, it's not the tool itself that's “evil”, it's how you use it.
