The individual’s incentives must be aligned with the group’s goals.To give you a quick example of nature creating incentives that lead to individuals pursuing their own interests that result in the advancement of the whole, look at sex and natural selection. Nature gave us one hell of an incentive to have sex in the form of the great pleasure it provides, even though the purpose of having sex is to contribute to the advancement of the DNA. That way, we individually get what we want while contributing to the evolution of the whole.

Reality is optimizing for the whole—not for you. Contribute to the whole and you will likely be rewarded. Natural selection leads to better qualities being retained and passed along (e.g., in better genes, better abilities to nurture others, better products, etc.). The result is a constant cycle of improvement for the whole.
