This is just my speculation but I bet it depended on wild animal populations, rainfalls vs droughts, peacefulness of neighboring tribes, etc. I don't think you can generalize on the happiness of all hunter gatherers.
For a useful perspective from the other side, you might want to read Steven Pinker's The Better Angels of Our Nature.
