Very true. But if your grandfather worked on a luxury building that neither he nor your parents could afford to live in and you manage to move in years later, you might be tempted to mention it to an audience as an American success story. Even if Michelle Obama's take on this is a little different, her comment doesn't rank very high on a list of things to be indignant about today.
Oh, yea it does. It is the heart of her anti-American orientation. Her ancestors probably captured the slaves that were sold to the Dutch to be imported to the US.
Debts of the fathers (grandfathers) are not the debt of the sons. If the Mooch got in there through merit, good for her but that is not the case.
