Americans still have a dim sense of their history, and stupidity like this can’t heap up forever without collapsing of its own weight and weakness.
Like you, I have been pondering this all for decades. Seems to me when you peel the onion enough to get down to it where we lost the struggle was years ago when we accepted the false wisdom of “responsible reproduction” and limited ourselves to “replacement procreation” and only had 2 children per family. While we were being “responsible” the Thrid World was reproducing like rabbits on resources WE sent them as “charity”.
IOW, we lost the struggle decades ago. Had we listened to our God’s instructions from the Bible and reproduced accordingly many of the problems we face would not have happened.
