First of all, I don't assume you've ever had to pay for any of the $hit you have right now, like that nice brand new computer with Windows XP, Microsoft Office XP, Norton 2002 Anti-Virus, and Adobe Photoshop 7.0, huh?
If you have, then you'd immediately know that all of that $hit totaled together would equal well over $1000.
So, either your family is very well endowed, and you're very stupid as far as saving money is concerned (considering all the upper-class citizens aquired their status through penny-pinching), or you're quoting something you heard your Economics teacher say, and thought you'd be noble in saying that.
Do you realize that Bill Gates ripped off a lot of people in his time? The guy that SOLD him MS-DOS, was paid around $60,000 for it. That's pretty $hitty, considering Windows 1-3.x, 9x, and Me are DOS based operating systems. They knew they were ripping that person off, but corporate America is all about ripping the other person off before they screw you over first.
Back to piracy. Piracy is what keeps companies progressing. Why do they keep releasing newer versions of Windows every 2 years? Progress. They're trying to keep piracy down by advancing our current technology. Otherwise development would go along as slowly or as quickly as Microsoft, etc want them to go.
