We look at values as something that is static. For certain universal values that is true. Example, kindness, this is a universal value and should remain constant.
But values, as defined by the cultures we live in, are constantly being changed, the rate of change if slow and hence its effects are not seen immediately. Values adapt too. In fact, these should change and evolve because cultures evolve too. Change is the only constant and if you try to keep the culture and values static they will conflict with the reality. Because times have changed and everything around it should change too. The hallmark of a healthy society where cultures, values, traditions keep up with the changing times and technologies.
