Yep, greed is a big time killer and unfortunately very little can be done about it, because human beings in general are greedy. There are very few willing to help others.
Come on now people, only spend money on items of absolute necessity, and not just because it looks good and you want it. If you don't absolutely need it, don't buy it. Take that money and give it to a charity or someone you know that really needs it. Think of others before yourself. I know I do, and you can too, let it come from the heart.
If you don't buy that new laptop, or television, or whatever, and millions of others do the same, corporations will be forced to lower their prices in the long run just to survive.
Lets just put corporate greed and the people who support it in a toilet, close the lid and flush!
