From my psychological point of view, this situation is very comlexed.
One for sure - the desire to have something, even something which is out of this world, is not bad itself. As a wish it can be a kind of a very good stimulant. And this is a good side of it with no doubt. We all have our dreams, and if we are also able to think about it as about a dream only, there's nothing to be worried about. But as a kind of an obsession, it is to be fight with help of a personalized therapy, sometimes even with e.g. tranquilizers. It is all about the source of this desire, and the way to make it come to the reality. If someone would like to travel space, and we know it is impossible (which still is, for some people), but this person takes is "for real" it is something we should be concerned about. It may be even a beginning of a psychotic process. I do not see the reason to feel the same about the people who e.g. wish to have a Rolls-Royce, and realize that it is just a wish. I would like to have it to, but I'm aware that my income is just too short at the moment. I hope there's nothing wrong with me...
