Robert Hughes, in his book "Culture of Complaint", hit the nail on the head
(in 1993!) :

"The all-pervasive claim to victimhood tops off America's long-cherished culture of therapeutics. To seem strong may only conceal a rickety scaffolding of denial, but to be vulnerable is to be invincible. Complaint gives you power - even when it's only the power of emotional bribery, of creating previously unnoticed levels of social guilt."
(...)
"In these and a dozen other ways we create an infantilized culture of complaint, in which Big Daddy is always to blame and the expansion of rights goes on without the other half of citizenship - attachment to duties and obligations. To be infantile is a regressive way to defy the stress of corporate culture: Don't tread on me, I'm vulnerable."
