There should be division of labor among universities in Hong Kong, i.e. some universities should be focusing on humanities, while others on sciences, etc.
- but: a division of labor among universities reduces diversity in those universities

- because: a division of educational labor among universities helps to allocate teaching resources in a more efficient way

- because: universities can concentrate money to develop the disciplines they are specialized in, resulting in better equipment
- but: previous investments spent on science research for a now arts universities will be wasted, and vice versa

- but: if the research has been published and disseminated it is not wasted

- but: (co) diversity is important to an university

- because: students need to interact with a broad range of people, otherwise they may find it harder to adjust to working with such people after graduation

- because: university education is different from vocational training, it aims not at specialization, but different possibilities of exposure
- because: division of educational labor among universities is a common practice in the world

- because: for example: MIT for science and mathematics, Central School of St. Martin for fashion design
- but: MIT does not concentrate only on science and maths, it has a School of Humanities, Arts, and Social Sciences with 12 courses, and the Sloan School of Management (web.mit.edu)

- because: specialization of universities' educational role helps to construct a better learning atmosphere within a university
- because: students will find it easier to discuss and exchange ideas of the subjects they like in their university life
