Actually I acredit the mindsets to the education system in the
70s and 80s, even to the early 90s.
At that time, during the industrialization, along with the booming
shipyard industry (apart from the recession in the 80s). Engineers
were in high demand. Hence, if you notice, the education system at
that time (even evident today) had a very strong grounding in Maths
and Science. Even in the Uni at that time, Arts and social sciences
were seen as dumping grounds during the 80s. Art students in
secondary schools at the time, were stereotyped to be less
academically inclined. Conformity was the aim at that time, which
resulted in less creativity. The workforce today, is made of
students of that era. Just my take.
