Is an 'Existential Crisis' a necessary condition to start on the path of Dhamma?

The path of Dhamma is a journey towards the end of all suffering through the attainment of Nibbana. The Buddha set out to find the cure for human suffering, but there are so many people around us today, suffering in so many ways. Most of the people end up still finding a cure in the material world. There are very few people who are suffering might end up starting to think about life itself as suffering for e.g. philosophers like Schopenhauer. But even these intellectuals don't seem to have come to the conclusion of the need to transcend the mind. As against there are those might not be in a lot of suffering but in an, existential crisis seem to arrive at the path of Dhamma. I am asking, is existential-crisis a pre-requisite and more fundamental human need than wanting to end suffering to start the journey towards Nibbana?
