I'm not a fan of her or her show, in that I've never watched or paid attention to it or her. However, if she's able to pile up loot by the truckload in our wonderful capitalist society, I'm all for it.
I'm a mail carrier and we have a running joke whenever the Oprah magazine comes out, one of us always saying, "Hey, guess who's on the cover of Oprah this month!" (She's on the cover of her own magazine every month.)
Actually, a good deal of this anti-Oprah sentiment is pure jealousy. You can find all kinds of reasons to dislike someone, but I just think that most of the real reasons people hate her is that she is very successful.
Interesting that there was a comparison between Oprah and Walmart. Walmart is extremely successful, but lots of people view them as an evil empire sucking up untold millions through unfair influence. Pretty much the same is true of Oprah.
In this, she's a lot like a televangelist.
