You cannot work with both parents fulltime when you have a toddler. Childcare is often only open 8 hours a day, so working 8 hours is not possible (remember mandatory breaks) and you also have to pay a lot for it. Also, single parents are increasingly common.

Poverty often means that you cannot afford a new washing machine when one breaks. Or not it being able to send your children to school trips.

As a German, I can tell you: 30k€ is not enough to raise a child here, even if both parents are working because at least one cannot work full-time.
