Which people and which geographical areas do you think benefited most from social technological and economic change from 1200-1500

The people that I think benefited most from the social technological and economic change from 1200 to 1500 are the Europeans. During this time, the Europeans created and utilized different mechanical devices including water wheels and windmills. Mills were expensive to make, but over time they brought great profits to their owners. Hope this answers your question.
