yes... voluntary exploitation. the whole point of capitalism is that any transaction requires both parties to enter voluntarily.
it's not always pretty (and needs regulation to prevent monopoly formation, which the US currently lacks) but the alternative systems with involuntary transactions are demonstrably worse.
If there are only two parties in the market, sure. That is rarely the case in any economic system, and can be argued that it is the least likely to occur in a capitalist-style system.
