Nesmith was 24 years old when the Monkees first aired. Before that, he spent about four years trying to make it as a professional musician. Unless you're implying that his mother should have bought him a career, or that he should have gone into liquid paper business, he had to do something to make it as a professional musician.
(Nesmith is a fascinating character, btw. Arguably invented both country-rock and MTV, produced Repo Man and ended up suing PBS--and winning $48m--for breach of contract/rights issues)
If you don't already have it, I would recommend 'The Monkees Day By Day' by Andrew Sandoval.
It's just like the cover says, it's a day by day account of the hiring, recording sessions and filming of the episodes up to Pool It.
It also touches on the various solo careers post Monkees.
Poor Peter Tork, he left the Monkees and couldn't get anything going after that and left hundreds of hours of songs and song fragments in the vaults.
