There are deep (and unresolved) questions about whether the neolithic revolution was a disaster for human happiness: once you have farms and crops, you can't run away from the thugs with spears... Hence the glories of the state and the church: it really does look like your average human lost a lot of autonomy and perhaps two inches of adult height once you switched from hunting-and-gathering to farming-and-herding.
But I don't know enough to evaluate or even have an informed guess on these issues...
