> At the end of the day, someone has to 'waste' money, in order for companies to earn money

I also used to feel this way, but I no longer think its accurate. This is most obvious in digital business-consumer goods today. Imagine I make a game. And it cost me about $100 to make this game. And you really want this game and would pay $5 just to get to play it. But I'm nice and sell it to you for $1. You certainly haven't wasted any money. And the fact I then sell it to 10,000 other people also doesn't mean you've wasted any money, nor they. Yet I've somehow made an immense amount of profit.

Even in the more difficult scenario of business to business material goods trades, it doesn't hold true. Imagine I sell iron and you need iron to make your widgets. It costs me $4 to produce a single unit of iron, but that's largely because I have an extensively refined and stream lined operation, and am able to benefit from an immense economy of scale. I sell it to you for $10. Well it seems that you must be wasting money, but the reality is that even if you bought the iron mine yourself and started producing your own iron you'd end up spending far more than $10 to create the volume of iron you need. So even though I'm again making immense profit, you're also not 'wasting' money in buying my iron.

This is why even huge companies are not entirely vertically integrated or producing their own supplies in other words. It's because buying from somebody else, even when that person is profiting immensely from the exchange, is not going to be inherently more expensive than if you did it yourself. And this is even true for simple no-skill goods like semi-raw materials. Get into skilled products, like semiconductors, and this all becomes even more true.
