Why Doesn't Contemporary Jazz Get Any Respect?

I am a huge fan of Peter White,Kirk Whalum,Dave Koz,Warren Hill,etc.I have never understood why this flavor of music gets no respect.Not only is it musically appealing,but in most cases its very well recorded.Any comparisons to old jazz(Miles Davis etc.) are ludicrous.Its like comparing apples and oranges.Can anyone shed some light on this?Any contemporary(smooth)Jazz out there?I would love to hear from you. Thanks John
