For most people in their teens or early 20s, it is unlikely that terrorism will affect their careers any more than it affected those of their parents. However, it is likely that terrorism will affect their lives more than it affected the lives of their parents.
Terrorism is not likely to have a direct effect on many careers. If anything, it will create a number of new career options. For example, there are many more airport security screeners than there ever were before the 9/11 terrorist attacks. There are also more people involved in things like the NSA’s surveillance programs than there were when terrorism was less of a worry. Terrorism has not, to this point, harmed the viability of many careers in the US and it has actually added some careers options for younger people.
Terrorism will probably have an impact on the lives of younger people, though. People who are young adults today have lived very little of their lives in a time when security was less prevalent. They will never live in a time when people could go to airport gates to meet loved ones. They will never live in a world where they do not have to get scanned in all sorts of ways when boarding an airplane. All of these little inconveniences will be part of their lives for the foreseeable future. Thus, their lives will be affected by terrorism more than their parents’ lives were when their parents were younger.
