dollar-gentsia
The dollar-gentsia are affluent individuals who assume their wealth qualifies them as intellectuals or people of unquestionable good taste. The wealthy, especially the nouveau riche, who attend opera, ballet, the the'-ater, museums and gallery openings when they'd clearly rather be watching CSI reruns. Rich boors.
Museums attract not the truely intelligent and knowledgeable but the somewhat educated, the middle brow, those aspiring to intellectual-chic, the dollar-gentsia.
