This is like asking why does entropy exist. Because that's the way it works. Add economic incentives that don't correlate with maintaining quality and that pattern is accelerated. Look at healthcare in the States for an example. Or Apple software quality for shining examples of expansive software efforts. I've sat having a beer with folks working on major projects we use every day and when I mention their product has a problem they defend it--really couldn't care less about the truth or their customer. Or maybe I'm just missing something. Silicon Valley is a brand. And software development is an arts and crafts effort--not engineering. This is a generalized comment.
