Money is a tool which can be used for the "good" or for the "bad".
Just that for many it seems to be like a drug: they don't know when it is enough and want more and more...
Money can solve some problems, true. But it also can cause problems.
It is natural to want some security, but there is no real security anyway. You still can get cancer, die in a car accident or what ever.
Every soul deserves to be happy, true, but happiness not necessarily has to do with material possessions, career and station. Of course a low-paid helper's job is not fun, and I wouldn't want to work until my hand bleeds just so that others get richer and richer, while I have barely enough to have enough to eat and a bed to sleep in. But I wouldn't want to be the owner of a company or a big Boss either, actually, this would be the least thing I want.
Wish I could have a more simple life. With enough to eat and all I really need for a healthy life, but without all this career, money, station... stuff.
