Most transactions are broadly a win-win - I have something you want, you have something I want, so we're both better off if we trade. That's the core justification for a free-market economy, and it's a very important one. Most, but by no means all. Some are outright fraudulent, because I'm lying about what I'm selling. Some are coerced, because I've used my economic, social or political power to rig the deal in my favour. Some have unpriced externalities - you need oil, I have a shale oil field, we're both better off but some other sucker ends up with flammable tap water. If we aspire to be ethical capitalists, we need to think about transactions in a more nuanced way than simply "free markets best markets" or "production good, consumption bad". We need to seriously examine whether the transactions we're entering into are genuine win-win scenarios.
