Great question. As you know, a thesis statement is the most important part of a paper. In light of this, let me give you a few suggestions in terms of a thesis statement.
First, you might want to argue that the Industrial Revolution caused the growth of the great cities of Europe and the world. In other words, you can look at the Industrial Revolution from the point of urbanization - crime, housing, formation of ghettos, and the like. This should be an interesting topic in view of what is going in our world today.
Second, you might also want to talk about the break down of the traditional family. As more people went to work in the cities, families were transformed. In connection with this, you might want to touch upon the social problems this caused.
Third, you might want to touch on the idea of what the Industrial Revolution did to agriculture, as most people were farmers beforehand.
