A common version of this is to complain about a lack of vacation time (even though you have 4 weeks, plus holidays, plus sick time, plus sometimes getting to work from home), as if struggling menial workers barely making above minimum wage are spending half the year in the Bahamas. [Note: this paragraph is written from a US perspective.]
"Golden handcuffs" is a similar term. It's not that there is no validity to these notions or that the phenomenon of golden handcuffs doesn't actually occur, because it most certainly does. It's just that, in their typical usage that I see, these terms are used to invent an abstract struggle that upper middle class people are supposedly facing in order to assuage guilt over their own fortune.
