Earlier quoted context omitted.
Sure, but personally I would argue that it almost always makes more financial sense to do a combined Masters-PhD (i.e. a research degree), especially in fields with plentiful funding. That was the case for me in Ireland when I did my doctorate.
Can you share which fields are these?
Generally, more hard-sciencey type fields tend to have better funding (physics, engineering that sort of thing). They also have less PhD students, because there are more opportunities in industry so less competition for places.
It seems like CS is one of those disciplines also, tbh.
