That would not be "better", that would be myopic: Practical skills are only a part of what an education is or can be; information and skills which are not practical are still quite significant for us and for society at large; practicality changes over time; and the determination of what is and isn't practical is itself quite contentious.

A lot of our education - practical or otherwise - may be useless fluff, or even ideologically biased. But that's mostly not because of the chosen discipline.
