Depends. Freemarket evangelists will say that competition fuels innovation, and eventually progress. Rand went too far (I hesitate to call her work philosophy), but people do have personal motivations and goals, involving material gain.
What I'm saying is that "sharing a surplus", which does occur, if "institutionalized" *, seems to deprive the society of one of its main engines. Then again cooperative movements don't by all means exclude healthy competition - at least from what I understood.

I say society - some might simply call it capitalism.
