No. The values can change but a relatively stable culture and society still exist. To equate changing societal values to societal collapse is a bit like equating a chapter ending with the end of a book. Societal values tend to change slowly, with the changes noticed more after they have occurred than in the transition. While an extreme and quick shift in societal values could bring about a quick societal collapse. Something like that would also likely coincide with other causes of societal collapse like war, a natural disaster, famine, pestilence. The insistence that a societies values do not change can also lead to societal collapse.
