They are the poor peasant who work on the lands of landlords and dependent on them for their basic needs whereas bourgeoisie are the people who are wealthy and have their own means of production. They are the ones who have most control on the economy and enjoy all the privileges of the society. The similarity between both is that they both struggled hard to create a place for themselves after creating their own identity in the society. They both tried to have power to keep them exists and grow in the society for example both tried to make their political parties to protect themselves from any kind of harms in society.
