Wow. Bit arrogant?

he's focused in on some specific minor financial transaction whereas I'm pointing out a fundamental aspect of capitalism.

Not even in the slightest. I brought up the idea that if an individual is willing to pay $1 for something that is valued at $1, that is an equal exchange. My company isn't losing money because they pay me $X. They are likely getting an equal or higher value from my labor than what they are paying out. However, its an agreed upon exchange of value.

Your argument is that in capitalism, in general, if one person is making a dollar, its because someone else is losing that dollar. Which is totally asinine. It doesn't take in to account the simple ideal of value.

If you have a broken heater and need someone to fix it you are exchanging money which you earned through time spent, for an equal exchange of labor. If I charge $80/hr and you're in agreement to that price, you are valuing a heated home to the money you're paying. Its an equal trade. You didn't lose money. You traded it for a service you valued.
