Because stealing really is such a self explanatory issue I'm really not going to elaborate too much more on it. But I want to leave my readers with an impression.
Stealing is any act in which you acquire something to which your are not justly entitled. It does not matter how you obtain it. In following this vein of thought, consider this. If you had a job in which you are really paid more that you rightfully need, and you neglect to use your means to assist those less fortunate, you are in a very real sense, stealing.
When you come to know the truth, can you honestly say that a corporate executives salary is justified in being higher than say a common farmers? Our society can create extreme economic disparities and injustices. But it is for us to do what is actually right. Someone who is well paid could just as easily help others as to line their own pockets. All the creation is loaned to us for us to use as we see fit, but when we seek to enrich ourselves at the expense of others, we steal that which does not belong to us. No matter the justification, there is right and wrong. And we know what is right and wrong. Learn the differences between your wants and needs, and use your means to do all you can to help.
