I think the existence of this wall is justified by economical reasons. The affluence of the western world is based on the fact that we can buy products built with the cheapest labour, say in China; but the cheapest labour can't come and compete with us for jobs they would do at a fraction of the cost.

I know I'm oversimplifying, but I think it's abhorrent that strict immigration policies go hand in hand with free trade. If you allow goods to move freely you have to allow the workforce to move as well.
