Rationally - yes absolutely. If there is a scarcity of tenants, why would you want to turn them away for any reason. I was talking in the terms of the human unconscious - the knowledge reaffirmed your entire life, and for as long as humans existed that stuff is scarce. And if stuff is scarce and that affects your survival - you might as well secure it for yourself and your group (the reason being that your immediate group is more likelly to support you, e.g arabs got a proverb about this - me against my brother, me and my brother against the men of our village, our village against another village, and so on). If resource scarcity could be alleviated through cheap energy, that might modify this base human survival mechanism which is a reason for in-groups/out-groups.
