There are problems with the analogy is that it starts at the end of the story instead of the beginning. It neglects to point out that the family's income is so low because the father decided about a decade ago that, having worked to get out of debt, he thinks it unfair that he is earning so much money and unilaterally cut his own salary because he felt he was earning too much and "it's the company's money." Instead of living modestly following that unilateral pay cut, he decides to spend lots of money that he doesn't have on cool shit that blows up and drugs and all the while refuses to take a pay increase notwithstanding that the family is spending shitloads more than it takes in such that the family now finds itself in the situation that it is in. Oh, and it also neglects to mention that father skipped town a few years ago before the shit really hit the fan
