No.
America still gives tax credits for children, and America has free school for children. One could argue being in a good school district requires being able to afford a good neighborhood I guess. But, that neighborhood is probably less desirable even if you don’t have kids.
You could be critical of laws that make children expensive like having to use a baby seat in a car. Or, having to vaccinate children, although many states help with that cost, or cover it completely.
Many employers penalize people who want flexible schedules, or who take years off from their career, but I think more understanding is given to parents in this situation then someone who isn’t a parent and just wants a more flexible schedule, or who decided to take time off from a career to travel and see the world or help a relative or be an at home spouse.
The way I see it a lot of accommodations are given to parents, and hopefully that will help people who aren’t parents in the end.
