I'm not so sure about that. Studies of the bones of pre-Columbian Indians in America showed that they suffered from repeated famine. I read an article years ago that women would spend all day kneeling grinding corn, and it would ruin their joints. They also did not have horses to do the heavy work. And used slave labor.
I don't think we know enough about the pre-Columbian Indians to make a solid evaluation about their lifestyle. Even estimates of how many there were vary by an order of magnitude.
It is hard to know what things were like as, horses, smallpox (and other disease), firearms, and other general dry goods (cast iron pans) all worked there way across mostly ahead of Europeans (or with traders who were not concerned about keeping the type of records we want and if they did keep records it was to sell their activities to the public back home (public might just be kings) and so they had reasons to make up a story for people who couldn't verify the story (and who mostly cared that the gold was coming so a false story that helped sell those people were evil worth destroying was welcomed)
What we know about their lifestyle was for the most part how they lived after all the above arrived, but each is expected to create major culture changes.
