Earlier quoted context omitted.
I don't know about "lower middle class", but in Manhattan and San Francisco, $110k is definitely "bachelor-class". You might not be able to comfortably raise a child, commute from Jersey to Manhattan, and make student loan payments on $110k/yr. Then you say, "well then don't live in Manhattan", which is probably true-but-not-obvious, but also implies you're going to take a wage cut to work somewhere else. And not eve…
You can easily commute from Jersey to Manhattan, make student loan payments and raise a child on $110k/yr. I did the first two on only $20,000/year (though I admit, my loans were a lot more sensible than those of the couple described in this article). You could also live on $110k manhattan if you are willing to live north of 111th st. A 2br 2bath up there ran $2100/month back during the bubble (less now).
(1) I'll spare you yet another hypothetical family budget monthly itemization.
(2) I'll concede that it is clearly possible to raise a family in New York on $110k/yr.
(3) I'll assert again that it is not comfortable to raise a family in New York on $110k/yr, nor does it appear to be easy.
There are obviously a lot of sacrifices you can make to make the budget work out, but in a family scenario, not all sacrifices are tenable.
