Hey, whatever you like! Who's more employable?
(1a) 17 years old; high school graduate; never had a job.
(1b) 22 years old; high school graduate; never had a job.
Or, if you prefer:
(2a) 17 years old; college graduate; never had a job.
(2b) 22 years old; college graduate; never had a job.
I submit that in every case the 17-year-old is more employable.
