IT, computer, engineering jobs could be considered unstable or unpopular. Healthcare jobs have the best job security. Being doctor or lawyer could be considered more popular or prestigious.

People are influenced by the media. Hardly any tv shows about IT, computer programmers, engineers, scientists.

Plenty of tv shows about doctors and lawyers.

Engineers have been laid off from companies in recent years. But doctor, nurse can work for a long time, anywhere around the world.
