20% more bugs? Or 20% less features?

People often make the argument that time to market is more important that quality. I’m not sure just what they mean by that. Do they mean that it’s ok if 20% of the features don’t work so long as they deliver quickly? If so, that’s just stupid. Why not develop 20% fewer features, and develop them well. It seems to me that choosing which 20% you are not going to develop and then choosing to develop the other 80% to a high standard of quality is a better management decision than telling the developers to work sloppily.
