Yes, she was educated and well-traveled.
However, JBK's family was conservative and Republican. Her father lost most of his money in the 1929 "crash" and aftermath.
He "blamed" Joseph Kennedy, who was head of the Securities and Exchange Commission for his plight. The family fell apart, thereafter.
Jackie lived with her mother after she remarried. Divorce and remarriage were not "encouraged" at the time.
Undoubtedly, all of this colored her perspective, opinions and "world view".
I agree that we have to look at the time and place and that opinions do change with age. Whatever her faults I do believe she was a great example to the nation when we needed her most. I could not have watched my husband murdered and then have to share his loss and my grief with everyone. Too much. And she said a few times in those tapes that she would not want to live without Jack. And Mamie---jeez it is not "your house" and from what I've read she was not the nicest person. No wonder Ike fell in love with Kay.
