An indentured servant is indentured as a payment for debt - the only way some people could pay their debts or raise money for other purposes was to indenture themselves.
Slavery is different from indenture. Indenture was a form of contract.
I know exactly what an indentured servant was. Most of the British prisons were full of Irish who’s only way out was through indentured servitude. Those indentured servants in the colonies were horribly treated and usually worked and starved to death and the women repeatedly raped. They were enslaved and treated worse that owned slaves, they were treated like rented mules who hardly ever lived to the end of their contract.
The sins of history are many—there is no way to re-pay groups who were victimized in some way. My ancestors were Irish, who England pay me for the potato famine of the 1840s? Should Norway pay me for enslaving the Irish in Viking Times? I am part English, should Italy pay me for Roman conquests? Its a foolish game and one played only for votes. Such pandering only makes us weaker and will help to bring down America. To blacks: Get over it! Listen to one of your own—Bill Cosby—and work to get out of poverty!
