African slavery was no different from nor worse than any other kind of slavery. There has been slavery all over the world for all time. The Muslims enslaved millions. They bought their slaves from blacks in Africa, they captured their victims at sea or they invaded countries in Europe for slaves. England enslaved tens of thousands of Irish and sent them to Australia. It’s been a human tradition to enslave others.
And many indentured servants were treated worse. Remember the first slave in this country was an indentured servant who was enslaved by a black man. He never signed up for slavery.
BTW most other groups of former slaves and even non-enslaved immigrants have been able to assimilate into the culture and have thrived. Blacks in this country seem unable to do that and want to blame it on something that happened over 150 years ago to people they never knew.
But there was a huge difference between African-slavery and European indentured service, and it begins with the fact that indenture was entered voluntarily as a way to pay off debts, and always included a set time limit.
Children of indentured servants were not themselves indentured, once their parents had fulfilled the terms of their contracts.
Yes, there were some abuses of the indentured service system, but it's estimated that between 1620 and 1776 about half of the 500,000 European immigrants came to America as indentured servants, fulfilled their contracts and went on to live normal lives.
Nothing remotely similar can be said of the 300,000 African slaves brought here in chains.
