Explanation:

The struggle of the social classes was a problem that appeared in the formations of a class of industrial capitalists, than a class of factory workers, whose only means of production were their hands and their children: a proletariat. The real wages of a small part of these workers had risen; food and health had improved; the duration of life had grown with the population. But the largest and most important part of the working population were very poorly paid, poorly fed, worse housed, eaten by the "fever of industries" and tuberculosis. From 1785, these workers gathered together, declared strikes that were accompanied by violence against the machines and against people (Luddism, will be developed later) and demanded that the parliament enact a protective legislation: the class struggle begins.

Along with such leaves problems, the provision of capital was unimportant. It was that most of those who owned wealth went to new industries, which started with small savings or loans and invested in the industry. They were tough, stingy and greedy, and therefore the workforce would suffer.
