There was an article on Slate Star Codex that examined this issue in detail. The conclusion was the opposite - basically that life is worth it even if living in extremely poor conditions - as evidenced by accounts of human survivors of e.g. concentration camps (the majority still wanted to continue living, and even engaged in normal human activities like love and procreation).

"Continuing to live" is a very different state than "being brought into existence," and I struggle to see how the desire for the former implies the latter. You can't ask anyone who was never born if they would prefer to have been created, nor can someone who was created observe what it would have been like to have never been born. It's difficult to even conceptualize non-existence!
