As much as I dislike the boomers the article about the me movement you linked is heavily biased and doesn't prove anything.
I agree that everything being about the individual has weakened society but think it more likely coming from the business class than people seeking therapy. Even the pope has come to a similar conclusion:
We must continue, then, to denounce the “dictatorship of an economy that kills,” and to recognize that “while the earnings of a minority are growing exponentially, so too is the gap separating the majority from the prosperity enjoyed by those happy few. This imbalance is the result of ideologies that defend the absolute autonomy of the marketplace and financial speculation. Consequently, they reject the right of states, charged with vigilance for the common good, to exercise any form of control. A new tyranny is being born, invisible and often virtual, which unilaterally and relentlessly imposes its own laws and rules.” [94] There is no shortage of theories attempting to justify the present state of affairs or to explain that economic thinking requires us to wait for invisible market forces to resolve everything. Nevertheless, the dignity of every human person must be respected today, not tomorrow, and the extreme poverty of all those to whom this dignity is denied should constantly weigh upon our consciences.
