That's nonsense. The US is all about children. That doesn't result in long term thinking about their education or maternal/parental leave but children are not seen as a nuisance.
I feel like in the US a century ago there were incentives to have more kids; need for labor, childhood mortality. These incentives have gone away and disincentives have taken their place; women entering the workforce, educating children until their mid-20s before entering the workforce as a career, and little things like the costs needed to raise a child[1]. We haven't really changed anything to improve those disincentives and the results speak for themselves. People are having fewer kids later in life.
