Maybe that will at least encourage some US universities to offer shorter PhDs like in Europe, where one year masters degree followed by two years PhD for a total of three years postgraduate isn't uncommon.
In Europe it is far more common to have 1.5-2 year masters degrees (half a year saved by overloading) followed by a 3-4 year PhD. It is almost a universal truth that a PhD shouldn't take less than 3 years unless there are exceptional circumstances.
I honestly can't believe any credible university is turning bachelor degree students into doctors within 3 years. Would love to see an example.
I don't know any three year examples. I'm sure there are PhD degree mill spots that'll give you the degree in a couple of years if you pay enough.
Depends on country, field, particular university or company, even the department. So you can't generalize over a whole continent.
