Hunter gatherers routinely starved to death, and had violent confrontations with other tribes. This is evidenced by the different propagation of Y chromosomes vs mitochondrial DNA, as well as other evidence. It was not better. It was just different, and ultimately less safe than living in agricultural communities.
