Pay extra for a specific seat on a plane? NOT!!

One airline already does it, more are thinking about it... the it, charging extra for a window, aisle, or exit seat. We already pay hundreds of dollars to board an airplane, but this would mean that everyone flying would have to sit in the middle seat if they wanted to NOT PAY EXTRA. What about planes with only 2 seats in a row? One would be aisle, one window - would you automatically have to pay extra? We no longer get fed, pillows and blankets are scarce if not completely gone, and now we should pay for the privilege of sitting in a very confined space for hours! Travelers can research the best seat in the house or on the plane as it were...
