While this is true, this process has also happened in our own culture, albeit a few hundred years ago.
In the UK the industrial revolution and agricultural mechanisation caused a huge migration from the countryside to the cities. Today, you can still see plenty of ruins of old settlements, cottages, churches, etc. which were abandoned and left to decay. In many parts of Scotland, you can walk to shielings, which were housing for herdsmen during the summer months. They would migrate there with their cattle and stay up in the hills, and migrate back down during winter when it was too inhospitable. They would have had a fairly boring and miserable existence. Living in relative isolation with no company but the animals, all food having to be brought in, and then long walks to the towns and cities to sell them. Today, cattle are kept in fields, fed with grass and cattle feed, and moved around in lorries. While there's a certain romanticism for the migratory lifestyle, and it might even be novel and interesting for a short while, I don't think the drudgery in the long term is something I could tolerate.
