Exactly. Computers are made in factories run by humans. Humans make mistakes. It happens.
Your computer did not fail, a file failed.
Apple can't help the fact that your 3k notebook had a corrupted file much more than their white macbook could have a corrupted file. They aren't going to say - "oh hey that guy only paid $900 for his computer, we don't care if his hard drive has corrupted files" They work their hardest to make sure every product has no flaws.
Why are you complaining so much, instead of working with Apple to get a new hard drive? It's not going to take 10 days to replace your machine. If you're in the vicinity of an Apple store - take it there. The whole procedure should take less than an hour. You could even do it yourself if you're such an "experienced" and "pro" user.
Apple takes measures to prevent and correct these manufacturing defects, but thing is - defects will happen. You just have to deal with the defects when you deal with human-made technology.
