We haven’t taken a vacation in 10 years. [...] We have no retirement savings, [...] We eat out maybe once every two or three months. Though I was a film critic for many years, I seldom go to the movies now.
They're not destitute, but shouldn't most people expect to get at least some of those things more often than that?
The lack of retirement savings seems particularly bad, as the author notes they used their parents' savings to pay for their children's educations. Their children won't be able to do the same.
And as another commenter has noted, it's not just a "woe is me" sob story, the idea is that the author is representative of a secret 47%(!) who are ashamed to admit how badly they're doing. The comparison with impotence seems apt.
