Occupational Prestige
Like medicine and law, the engineering profession carries with it a certain amount of prestige. Because of the difficulty and importance of their work, engineers are typically well-respected both by other professionals and in society at large.
The prestige associated with being a professional engineer can be especially useful if you decide to start your own business or move into consulting work, since your status as an engineer will automatically grant you a degree of trust and respect amongst your peers.
