We've spent the vast majority of our existence as a species living in small pre-agricultural bands in which it was virtually impossible to accumulate real personal property or wealth. Consequently, a person's status was determined not by how much they owned, but rather by their merit and relationships with others.
Wheat is a relatively recent development in human history, as is agriculture in general. It changed everything but for better or worse, agriculture is a trap, and once you start transitioning to it, you can never go back.
It depends on how you measure it. People living in small-scale tribal societies tend to be universally happier than people living in big industrialized societies, but they also face a lot of problems and challenges that we've eradicated through technology.
