The capitalist system, so far, has been the best at optimizing scarce resources.
I would be careful when you say that once you realize that capitalist economies also exhibit the greatest amount of waste - wasted food (look in the trash of any restaurant), wasted resources (disposable products), etc.
For example, millions of gallons of oil are wasted each year on bottled water because the bottles are used once and discarded to landfills. Single use products, like water bottles, made from finite resources, like oil, are not an efficient use of resources.
