Can someone at Fox please explain what Michelle Obama means with her Mantra we are high and you are low

 What does Michelle Obama mean when she repeats (although you can't repeat something that has no substance), 

What exactly does she mean when she cites her High/Low mantra; does she mean it in a Cultural sense; we are High Brow (if prancing about in a car with the beefy James Corden
is'High Brow' then what is being in a car and reflecting on Beethoven
(in Michelle's value system that probably be 'Low Brow')

Beside isn't it incumbent upon the First Lady to display decorum, 

Dos she mean High/Low in a Zoological sense,  Democrats are playful Dolphins, while Republicans apart from being deplorables are just well
undeveloped as a species. 

Come on you Fox political gurus - time for a little deconstruction instead of just 

reportage, leave that to the NYT
