Yeh, it is useful, one of my degrees is in Economics, however, you can probably learn most of the basics by just picking up a basic micro and macro textbook and reading it yourself.
Masters, generally focus on one specific area, so you will not really get a base understanding from what I am aware.
The entire process of Uni is more just for the paper so you can 'proove' you can research and present information at a University level. So definately helpful if you may want to work in the field one day, but other than that, I would say the things even someone like Radge states in his analysis are very very simple if you just learn the basics.
