What's with the French and their apparent disdain for money/success?

I've seen many French movies (and this one belongs in the same category) where successful wealthy middle class people are portrayed as being extremely oppressed by their success/fame/wealth/position. These petite burgeois characters are always and invariably extremely annoying, whiney little pricks, like the pianist celebrity in this movie. All this guy was doing throughout the entire movie is desperately trying to run away and escape his fame/success, only to fail miserably. Say wha'?

I mean, come on, how hard can it be to screw things up in life? If you find yourself in a position where you've managed to succeed and outperform your competition, and now you're miffed at your own success, it will be incredibly easy for you to mess everything up and to get people to boo you off the stage. But no, this guy was really, truly trying very hard to get people to boo him off the stage, he arrogantly and disrespectfully interrupted his high fallutin' performance and launched into a cheesy strip tease routine, and yet the crowds still adored him. Wtf! How frustrating can that be (and how stupidly unrealistic)?

French cinematography is full of such unbearably lame cliches, and one must wonder when will this madness end? No, it is not true that people hate money and that they cannot find ways to get rid of their money. This thing never happens, unless you immerse yourself in the phony bizarro world of French petite burgeois cinema.
