False, progressive Democrats mainly care about a growing middle class, heck that's their number one issue.
They want a better educated public, livable wage, universal healthcare, increase wages, strong unions etc... all of that benefits the middle class not the ultra rich.

look at the the top ten places were economic upward mobility occurs and the top ten worst. What do they have in common?
9/10 are Democrat leaning areas, where upward mobility to middle class and upper middle class occur. And the tenth one is considered the most liberal area of Utah.
What about the worst cities, states for upward mobility and middle class growth? You guessed it 10/10 conservative places.
