Mathematically what you say is true, but then if the majority of the parks were sold to save the few, Kent would be turn into another disgusting city like downtown Bellevue.  Imagine nothing but concrete and steel no matter where you look, because that is where Kent is headed soon.    I think there could be far better ways to keep the parks, but then everybody wants to have their cake, and then eat it, and nobody wants to talk about the real reasons why this city is declining.
