Go look at the document itself. It's linked from the article I posted. It's pretty clearly meant for a single person. There's not a word in it about "you and your spouse", it's just "you". And the budget itself says "2d Job". If it meant your spouse's job, why wouldn't it say "Spouse's job"? Second job to most people means, well, your second job.
But as others have pointed out, even giving them the benefit of the doubt that they did mean a two person household, that makes it even worse, because now they're expecting 2 people to live off of $800 and $20/month healthcare (the cheapest plan McDonald's offers, by the way, is $12/week, or $46/month - more than double what they put in their budget).
It's just hilariously, and tragically, bad, and there's no way to spin it to make it good.
