The question of which type of economy would better benefit the idea of sustainability is a complex one. I believe that the ideas and characteristics of the capitalist would be better suited to the idea of conservation. The ideas of Marx and Engels that natural limits can be overcome by science and progress lends itself presently to the movement on the right, which is more capitalist than socialist. The idea of "wise use" is heavily debated among environmental scholars. What constitutes a "wise use" of a resource? To answer this question we must first decide what resources should be used at all and which ones require strict control and perhaps restriction on use. A socialist would say that the resources that are to be used should be used by the masses equally. This thought pattern, in my opinion, would lead to a more widespread misuse of resources.  The more people using the resources the faster they will be depleted. It almost seems to me that a socialist approach would mean that the government would have to decide that either everyone has access to everything equally or no one has access to any of it. In a capitalist economy, there will always be the "haves" and the "have-nots", and resources will be less used when only a percentage of the population is using them.  I know that this idea is very elitist, and since I am one of the "have-nots" as a student-mom of 5 children, I feel that I can have this opinion.  If I were one of the "haves" I would use as much and as many resources as I get like.  So, the capitalists would be the better option for a more sustainable world.
