No doubt and a big problem is that our culture values things too much. . We encourage the young to pursue jobs not family. The average women’s fertility starts to decline at age 25. Most people get married after that age. It’s a recipe for extinction. We will get replaced by people who don’t do that (like Muslims).
And it'll happen sooner than we'll think. Just take a look at the UK. Maybe 2 or 3 generations.
