Strange Travellers as a whole

So if all the stories tie together into one big message Wolfe is sending . <SPOILER SPACE> . . . . . . . . . . Would that message be that life is so hard and unpleasant that delusion is preferable to it? If that's true, what's interesting to me about Wolfe's worlds of delusion is that none of them are paradises. The traffic jam. The battle of good vs. evil being a suicide mission in space. The frozen world of Emery. Yet still they seem to be more appealing to the main characters than the real worlds they exist in full of boring jobs, mundane family duties (fatherhood), divorce etc. Dennis/Endy
