It's perfectly evident that this matter is complex and migrants are driven by many factors but one thing which is obvious is that they wouldn't choose to live in squalor in Calais for months or years just to risk their lives under a lorry trying to get into a country in which they believe life will be worse.

The extent to which what they've been told/choose to believe about their prospects in the UK and what is true differs will vary from case to case but, whatever their reasons and motivations, the more we allow to come here and remain, the more will want to come and the more desperate they will be. Something will have to give at some point - it's just a question of when, not if.

Until we do something about the reasons these people are coming half way around the globe to get here they will continue to come and in increasing numbers. The empirical evidence is that, for these migrants, life in France (and elsewhere in safe European countries they've passed through) clearly isn't deemed attractive enough. Why would that be? IMHO it's a combination of factors chief amongst which must be the overriding belief that they'll do better here and be less likely to ever be removed.
