In most cases, yes. But you have to remember, this is Valve and not some ordinary company. They have extremely deep wallets and a lot of responsibility and expectations on their shoulders (importantly, not the stock market!). If they charged what it cost for hardware and what it cost them to do r&d, it would likely not be in consumers favor.

Like even just get off the American-bad thing for one second: pricing it as a standalone pc basically just means "the cost of the parts". They've put a lot of time and effort into this across their core employees and likely outsourced stuff because they couldn't, in-house. Actually listening to people and charging relative to that is actually a great way to be fair and make people happy, guaranteeing positive impact of your product. I guarantee they're paying attention to what people say ALL over the place. Like.... Why do you think "it's done when it's done" is their pace?
