What social groups were responsible for the formation of the bourgeoisie and hired workers?

If we talk about the bourgeoisie, then this class was formed from those who were a merchant, engaged in the trade of various things. Also from those who held a high social status in society. These were landowners, landowners, in a word, those who had some kind of capital and realized that it was possible to earn money on the production of certain items. But the hired workers were formed from the peasants. Of those who were serfs, because they did not want to just work for the feudal lord, but go to the factory and work for money, thereby forming a new working class.
