The plane really isn't the issue, it's her thought processes and "entitlement" that has removed her from the every day American experience. Whether it's that you can pay cash for all your groceries and not have to use a calculator to keep on budget, or use food stamps, there is a gap that leads to misunderstanding where each of us has a challenge or concern.  
As George H.W. Bush was unaware of bar codes in the grocery store check out line, that showed how out of touch he was, the assumption that everyone has a plane is equally showing how she is not in touch.  She doesn't just need to sell the "damn plane".  She needs to spend a few days in the "hoods" of her constituents, go to the schools, hospitals and homeless shelters to see the needs of people.  Too bad, she's a Dem. and I count on her to be part of the resistance, but she just doesn't get it.
