That will change with government policies like Poland’s 500+
Poland can go and dream up whatever policy they desire, but I seriously doubt that their birthrate will be bumped up much.
The prevailing attitude around Europe is to open doors for women to get into jobs and careers. That means marriage occurs later in life for a large portion of women, and they use first-class medical care with birth-control options to ensure their career goals are met. All of this leads onto families with mostly zero, one or two kids.
One of the key factors in the Poland plus-up...was the desire to make child-care as low-cost or free (as possible)....which means you need to raise taxes to cover this benefit. Eventually, this tax issue will become front-page news.
