Does it seem right to you that "Grandma Obama" aka "First Grandma" will receive 160k a year, lifetime pension for taking care of the grandchildren?

I’m an Obama fan for the most part but I agree that this seems excessive. Even if she were paid, if she’s receiving 160k a year as a pension, she received way more in salary.
