All too often in modern times we find it easy to see money as the problem, the root of all evil. The people who believe that seem to ignore human greed as a factor, specifically excessive human greed.
In my books there’s being greedy, then there’s being too greedy. Greed on its own is basically the desire for more material prosperity, usually more than you need or supposedly deserve. This is actually good in healthy doses, but problems start when greed goes too far. You know, when people start flying past the point of excess and go straight to self-destruction, when people starting blowing off their own ethics and even other people, when people start seeing money as the centre of their world rather than as the means to the goal of personal prosperity. Greed becomes a problem when you fail to manage it and it becomes destructive for both yourself and everyone else. Thus, like many things, greed is good if kept in check, but I’m guessing many of the rich don’t bother thinking before they acted. Really, ignorance among the few true evils.
To be honest, I can’t escape the thought that much of our morality when it comes to accumulation of wealth is basically just there to keep the majority of people poor. We tell the poor “you shouldn’t be greedy”, or “don’t ask for more”, or “be happy with what you’ve got” in order to prevent them from wanting to become rich and keep them content with their current circumstances.
