Earlier quoted context omitted.
Ah, but you can be a researcher (doing work at least as good as most PhDs) without a PhD. Therein lies the rub.
You can also be a good, e.g., mechanical engineer without getting an engineering degree, but this is an exception to the rule. Also, companies use the degree as an indicator of skill, so the good engineer who doesn't have a degree needs to somehow reliably demonstrate a solid understanding of the field to compensate. Obviously, from the company's point of view, one is easier to deal with than the other. The same appl…
That's an awfully incorrect analogy. Enrolling in a PhD program has absolutely nothing in common with getting an engineering degree. An engineering degree is conceived to give the students a pre-established set of skills and technical knowledge that meets industry demands.
A PhD program is set to help the PhD candidate research a very precise and specific topic, which more often than not is entirely irrelevant to any industry, so that in about 4 years he is able to produce some scientific findings and defend a thesis in front of a jury.
The key difference is that an engineering degree is tailored to teach marketable job skills while the PhD program is the exact opposite.
