I notice she has a roof over her head, paid for by taxpayers (which doesn't include her due to her income, which probably qualifies her for earned income credit). Her baby has free healthcare, and her food costs are subsidized, again paid for by taxpayers. All in all she is probably living on an equivalent 30,000 dollar a year income from McDonald's and the taxpayers.
Bernie wants a basic living fund for all Americans rich and old at 31,000 a year. So this young woman would actually be making 61,000 a year and everyone in America is happy. Lol.
