marxism and social classes

so instead of slave and slave owner the freed and the non freed. social class begun where middle class was bourgeoisie and working class was proletariat which is low class. the bourgeoisie owned all the manufacture industry factories and the proletariat worked for them. the bourgeoisie had the working class working in a bad work condition. such as bad health conditions. there was no job security they could fire you at any time for any thing if they felt you were no longer needed. tools uses were dangerous and there was no safety measures to ensure the life of the workers. there were no emergency exists or windows so they were breathing in all the fuels and smoke that the machines were giving off even though it was harmful. so like usual  you cant keep the oppressed down because they turned on them and rioted and refused to work under those conditions. like today's society though there are rules and worker laws some people still are oppressed and ran by the 3% and we riot banks and other things to get what we want though it hasn't really worked we try.
