Graduate School: to go or not to go?

A debatable article by the Economist leads to various arguments, as follows:-

Doctoral degrees: The disposable academic | The Economist -  http://ow.ly/3IJZN

In accordance to this, there are other articles may be of interest, such as:-

100 Reasons NOT to Go to Graduate School - http://ow.ly/3KOMk

Career Advice: We Ignore 'The Economist' - Inside Higher Ed -  http://ow.ly/3KONJ 

Of course, some arguments don’t really apply to subjects like science, technology & math.

Anyway, read the article with open minded. No right or wrong in this issue, follow your will.
