It will be of little avail if we achieve economic growth long term and attain a European standard of living without attending to the social issues. But we cannot handle them properly without such growth, and would even quickly increase their severity.
For example, one could deal with the question of social gaps by means of drastic hikes in taxes and transfer payments, but such a policy would also have a serious adverse effect on growth, and after a few years this would lead to a situation in which we would all be more equal, but also poorer.
