Skirtboy is quite right.
The trust associated with getting degrees in very technical subjects should not be underestimated. Particularly in areas with tough security and health requirements.
You could in theory teach yourself all you need to know, but from an employer's point of view it will be a much bigger risk to employ you. You can tackle the problem with getting loads of certificates and etc, but I am sure that's long-winded and expensive as well.
