On a slightly different note, I wonder how much fiscal "constraints" play into this. Think of rather small businesses who are unable (or probably more correctly unwilling) to procure adequate infrastructure to support truly good testing and QA.

I can imagine managers and directors saying, "What? You want another SQL Server license just for testing?"

Yes, it's a matter of "how can you afford not to" and the advent of better hardware and VMs has made this less of an excuse, but management and the bean counters don't always see that. They tend to have a bit of bottom line tunnel vision.
