50 million abortions need replacements for the actuarials to hold.
That’s the tip of the iceberg, and spread over half a century. The number of American adults opting out of parenting is frightening; I understand it, and it is their choice, but these are the consequences.
My town years ago put in soccer fields for the “replacement Americans” and a dog park for the Americans; as our “Main Street” businesses disappear they are replaced with taquerias for the replacement Americans and pet food stores (”bakeries”) for the Americans. This change is rapid and won’t alter course.
