What is "actual slavery" and "actual masters"? In the external, physical world everyone is a slave in one respect or another. The slave owner of the American South had to manage his estate to turn a profit. He had no Internet, no machinery, no motor vehicles. The black slaves were given better living conditions in many instances than they would have had as a "free" Africans, which of course is a myth since the Atlantic slave trade was based off of a preexisting African slave trade and in all pre-industrial societies, including in Asia, slavery and serfdom was the norm, since the economic conditions did not yet exist for what you perceive today as "free" wage labor. Bill Gates and Jeff Bezos are slaves compared to the 23rd century super-Chinese that haven't been born yet.
At every step, at every level, there is a slave morality and a master morality. You want to "overthrow your master"? If you are a slave inside, you will never be free. Look at the Haitian Revolution. They sure as hell overthrew their oppressors, didn't they. Ended slavery, gained political autonomy, declared white people barbarians, raped all the white women and killed all the white men. Today their per capita GDP is $719 (literally, I just looked it up) and they spend their time periodically begging white people they revolted against for charity. THEY NEVER STOPPED BEING SLAVES.
