A Better Place?

If everything is subject to change, what use is it to make a utopia, or a ‘better society’ – when inevitably this society will someday decay, alter, or be destroyed altogether? The reason why I do not care for ‘making the world a better place’ is because it will inevitably come to an end eventually. I see no reason why I should waste my time and energy trying to improve something that will someday be subject to change. Even if you do create a better world, it will eventually be destroyed somewhere along the line.
