Why? We are ina world in which, to the best of our knowledge, most things ARE constant. The forces of nature are the exact same now as they were 10,000,000 years ago. Tomorrow, gravity, electromagnetism, etc. will obey the same laws as they always have (after the first few microseconds of the universe, anyway).

To think that the driving forces which all living things obey, and have always obeyed, will suddenly, magically change is ridiculous. There is not a single rational reason to believe that gravity, tomorrow, will function differently. Nor is there a single, rational reason to assume that the laws which govern living things will change, either.

I believe that, there's no such thing as the ``human nature'' (note the b-word). Human is affected by situations, circumstances just like is the composition of a water as it flows from the mountain, through a valley, across the fields to an ocean.
Yet, it remains water. It changes, and in different circumstances, it has different properties, but water still obeys the physical laws governing water. In the same way, people can have many different properties, and in different circumstances we can become different people, but we remain people, and still must obey the universal laws governing life.

Further, if humans really did change enough for the entire world to accept communism, we would deserve to go extinct; we'd be halfway there already.
