Slavery in the Roman Empire
The slavery of Paul’s day was fraught with abuse. William Barclay writes of the evils of slavery in the Roman empire during the time Paul wrote this epistle to the Ephesians.
“It has been computed that in the Roman Empire there were 60,000,000 slaves. In Paul’s day a kind of terrible idleness had fallen on the citizens of Rome. Rome was the mistress of the world, and therefore it was beneath the dignity of a Roman citizen to work. Practically all work was done by slaves. Even doctors and teachers, even the closest friends of the Emperors, their secretaries who dealt with letters and appeals and finance, were slaves.
Often there were bonds of the deepest loyalty and affection between master and slave … But basically the life of the slave was grim and terrible. In law he was not a person but a thing. Aristotle lays it down that there can never be friendship between master and slave, for they have nothing in common; ‘for a slave is a living tool, just as a tool is an inanimate slave.’ Varro, writing on agriculture, divides agricultural instruments into three classes—the articulate, the inarticulate, and the mute. The articulate comprises the slaves; the inarticulate the cattle; and the mute the vehicles. The slave is no better than a beast who happens to be able to talk. Cato gives advice to a man taking over a farm. He must go over it and throw out everything that is past its work; and old slaves too must be thrown out on the scrap heap to starve. When a slave is ill it is sheer extravagance to issue him with normal rations.
The law was quite clear. Gaius, the Roman lawyer, in the Institutes lays it down: ‘We may note that it is universally accepted that the master possesses the power of life and death over the slave.’ If the slave ran away, at best he was branded on the forehead with the letter F for fugitivus, which means runaway, at worst he was killed. The terror of the slave was that he was absolutely at the caprice of his master. Augustus crucified a slave because he killed a pet quail. Vedius Pollio flung a slave still living to the savage lampreys in his fish pond because he dropped and broke a crystal goblet. Juvenal tells of a Roman matron who ordered a slave to be killed for no other reason than that she lost her temper with him. When her husband protested, she said: ‘You call a slave a man, do you? He has done no wrong, you say? Be it so; it is my will and my command; let my will be the voucher for the deed.’ The slaves who were maids to their mistresses often had their hair torn out and their cheeks torn with their mistresses’ nails. Juvenal tells of the master ‘who delights in the sound of a cruel flogging thinking it sweeter than any siren’s song,’ or ‘who revels in clanking chains,’ or, ‘who summons a torturer and brands the slave because a couple of towels are lost.’ A Roman writer lays it down: ‘Whatever a master does to a slave, undeservedly, in anger, willingly, unwillingly, in forgetfulness, after careful thought, knowingly, unknowingly, is judgment, justice and law.’”
Bible outlaws everything except slavery. No fornication, no adultery, not stealing, but enslaving your fellow man, 
Old Testament has laws about how long your hair can be, but nothing against slavery, SEEING AS THE HEBREWS USED TO BE SLAVES???!!!!!!!! 
Paul telling the christians to fly under the radar and be good slaves... why wouldn't he give the same advice to the Black slaves in America?
So because he uses the same word "slave" it means the same American slavery?
Nope, the slaves Paul was writing to did it voluntary. During American slavery many/most was based on kidnapping, forced labor. Along with rape, teaching that we were less then human because of our skin color. To compare the two is 
But read the beginning of that chapter brother. And you'll understand the property word, brother.
