I can't say that I'm familiar with the Polish university system.
I think the most important thing that Polish universities would benefit from would be transforming their structure to resemble that of the best American and British Universities which are always at the top of the rankings:
But this takes time and money of course.
Positive thing about Polish Uni's is that they are less "political" than many other European education systems and so called "gender studies" are not as popular in Poland.
Why would someone waste 5 years of their life studying this just to become a barista in the future is beyond my comprehension.
