Playing devil's advocate, all this fear and anxiety (as @coldtea properly states) is an engine of the economic machine of the western world. What I'd argue is that is all twisted for idiotic reasons. For example, it would be good to have fear of death used to push society towards things like cures for cancers. And anxiety used to push ourselves to reach our potential instead of seeking validation in superficial things expressed in Instagram pictures. But we humans like the quick fix and the advertising lobby delivers. We have 50% of the blame here. Same with the unhealthy foods and drinks we take all the time. To improve our behaviour we need incentives like most animals.
