I have one friend, who graduated from electrical engineering school at San Jose State that went to San Francisco State for a MA/MSci. in electrical engineering. He could not find a job and have lots of spare time and live with parents, so why not? If you wrote a thesis about an electrical device, circuit, or electrical material, then an employer might hire you for your speciality, otherwise, you will wait in line like the rest of us for a job. A Ph.D or even research experience makes you very specialized, but it will reward you with a job only if that business happens to need your speciality. A stereo company is not going to need someone who worked as an assistant in a selenium copper compound research place. Ph.D is a go way to get into all levels of teaching, except children to teen age schools, that require a child development and teaching credential, a different school. Teaching at a college to university usually best with a Ph.D, than a MA. Governments in the U.S.A. could not afford to hire teachers with the depleted budget. If my friend has nothing better to do and has some money, then a MSci. or MA classes are best for him, but not me. I used to work as a research assistance with selenium copper based compounds for better electrical conductivity. There was not a commercial value in it to make money, that it was a topic for academia research and study. Universities usually do a topic that industry have little interest in, because the profit is not assured and working products are unknown. School can make you go broke, expensive and time consuming venture. As mentioned by others in this forum, academia have a life style that is not like going to work or experimenting and building an amplifier in your garage or room. Industry is not solely emphasizing or interested in your Ph.D., but what you can do for them to make a profit and you get a fraction of that. If you have a Ph.D., great, but you might find your self soldering and plugging things in and answering the telephones, too. You might find yourself without work as some employers are only interested in years of work and under whom, than your Ph.D. experience. Do not feel discourage, if you want to try it, then try it. I do not live in Italy, so I cannot help you. San Jose State does not grants Ph.D., that you will have to Cal UC Berkeley or Stanford, California.
