R.A. Heinlen is great! Here's my favorite quote:
"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."
Do I count as a human bean?
He was ahead of his time, for sure. I tended to like his earlier stories, like Farhams Freehold and Farmer In The Sky.
If you want to read a good book in this mode, read Jerry Pournelle's Starswarm.
Heinlein's later books were a abit unreadable to me, but I understand these are what many consider his classics.

Karl Marx had many of the same sentiments, actually.
