The libertarian leaning policies of the USA have already started to create a low birth rate. The first affected generation doesn't have time to realize that they will be worse off than their parents, and so has 2-3 children without realizing that they will be unable to afford to educate or provide healthcare.

Those children then grow up seeing the hardships and stress of their parents, who complain about how expensive they were and now they won't be able to retire and decide to either wait for things to get better before having children or not to have any at all.

Then the elder statesmen complain about low birth rates.

Until the United States creates policies so that someone who works 40 hours a week, regardless of the job, will be able to retire and afford healthcare, only the top 10% of earners ($150k+) and the extreme poor (medicaid, food stamps, subsidized housing) will have more than 1 child.
