My dream system would be American universities (all get the same high school degree, take a test to see which uni you can join) mixed with the German trade system (proper standardized apprenticeships that are paid with further education for anybody be it plumber or electrician at Siemens, Bayer or BMW).
We have more or less this in France with all the other schools (universities, engineer schools, vocational schools, ...) where the last 2 or 3 years can be done as apprenticeship. Very sought after.
I always have 1 or 2 apprentices in my teams, at very technical and engaging positions. They are happy, I am happy.
