That is a starting pay and yes you cannot rise a family on starting pay, nor should anyone expect to.
This is not about what people start at but what they can achieve and how best to get there.
Most trades will start low but the motivated skilled craftsman can make bank. The entrepreneurial one can achieve real wealth.
Sorry, explain how that works for an individual, not everyone has a family and it is no more affordable for a single person. What part of those monthly expenses go away when no family is present? Do they get to skip car insurance? Water & sewer? Rent?
