I have always thought that in front of a countable noun we have to use 'few':
fewer jobs etc.
But today I came across this:
Facing more economic pressures and less funding from state legislatures, public institutions find themselves offering less classes.
The article is called 'Try to Guess These Four-Year College Graduation Rates' by
Lynn O'Shaughnessy from CBS Money Watch com.
The sentence appeared in the comments section.
Should it not be fewer classes instead of less classes?
Thank you for your time and help.
