I agree - I feel the "post-happiness world" that they're talking about is really just people attempting to find happiness through money and possessions as defined by other people/groups, and validation of that happiness through social media. The most happy times and happy events in my life may get a mention on my social media; but the truly happy memories and feelings come from things outside of what I expect to post publicly. I think what people need to focus on is what has made them truly happy, without direction from others (NYT or otherwise) and without any public validation of their happiness.
