I fully agree with this point. People here argue that minimum for scientist should be cut down to something that fits into strictly vocational degree that scores them a well paying job.
Every scientist in any STEM field I know knows "the minimum" that is larger than what fits into masters degree in their field. Someone with PhD is basically still scientist in training, a junior. 8-10 years of basics then very special knowledge above that sounds about right.
My background is in EE, so I think that being an engineer has prestige but it's not the same as being a scientist. Good EE engineer knows different things than research scientist in the field. You need to know enormous amount of theory and math to design modern circuits and radio interfaces but designing them is engineering.
