The cynic inside me would extend this problem to the entire economy or even human society itself. Any economic transaction is supposed to benefit both parties: the buyer offers an amount he is willing to pay for what he wants, the seller provides his goods or services at a price he is willing to accept. As PG might say, wealth is created in tandem with creating stuff that people want.

The problem is that some elements in society have become extremely effective at creating a perversion of "stuff people want" for their own benefit. They exploit loopholes in the system, whether by preying upon the poorly-informed, shifting costs onto externalities that we can't price properly, engaging in corruption, or producing items of questionable actual value but very attractive perceived value. They take advantage of our desire for easy answers to our problems with minimal effort expended.

Case in point: Ponzi schemes, coal power plants, Halliburton, the tobacco industry, Zynga, and even to an extent, religion

We've tried to control this with laws, education, and social norms, but ultimately it seems the invisible hand reigns supreme.
