The core principle behind the economic culture is INNOVATION.
Innovation and its effects...
At the epicentre of this paradigm shift lies innovation, referring to new ideas that catalyse changes on a large scale. In this instance it is defined as 'better solutions to existing problems, and solutions to problems that we didn't know we had'. As we solve larger problems we discover more interesting and complex problems to solve. So we put forward an interesting and thought-provoking way of looking at the world that we live in; this is commonly referred to as 'egotistical altruism'.
Why should we help develop other communities?
It is in your personal, selfish, best interests to aid developing nations, local communities or even less well-off areas around you. In a positive-sum-game, due to the supply and demand mechanics behind innovation, your own life gets better if more people around the world even in countries that you wouldn't know existed have better lives.
Let me explain...
Due to the essential nature of innovation, the more people want something and the more people are able to contribute to it, the more likely it is to happen. For instance:
Cancer treatment
Currently, one in six people die of cancer or cancer-related illnesses. If we have a third of the developed world searching for a cure this may take them 30 years. Whereas, developing nations are less able to contribute to the search as they have more immediate issues to deal with, for instance, simply feeding their population.
How do we make the cure come faster?
What if the developing world weren't... well... under-developed... then that proportion of the developed world grows. If it tripled in size then there are three times as many people working on it and the time until we have a cure would reduce by a factor of three. We now have our cure in 10 years, not 30 years.
