The OP's question gets at the heart of a debate that has been simmering here, in various forms, for the past two years. Namely, is the system broken?
Everyone here is trying achieve financial independence so they can be free of money worries and focus instead on their real priorities. But the way we go about doing that is to focus primarily on money worries, even at the expense of their real priorities.
Search the forums for terms like capitalism, ethics, evil, social funds, distribution of wealth, and you'll find many long running conversations about whether or not profiting from the suffering or stupidity of others is right. Lots of people here have chimed in on both sides of that argument, and I generally think we're each obligated to follow our own moral conscience.
If your moral conscience thinks it is okay to get rich by strangling kittens, that is your decision to make and my opinion of it shouldn't really matter. I see only shades of gray between kitten stranglers and derivatives traders. Deception and exploitation are the very basis of capitalism, the most successful and prosperous economic system in recent history.
In this game, the cheaters win. You get decide how important "winning" is to you.
