I'm one of these folks. I think it's wrong to blame this solely on COVID. I won't have kids because my position in the United States is nowhere near guaranteed. I have survived three economic recessions, one of which I lost everything in and the course of my life was permanently altered. I watched as society adopted "the internet" and used it in terrifying detail. I've watched as social problems turned into vitriol, anger, and at times violence. I've watched as climate change was viewed as either "conserve", "don't believe", or "innovate" with the latter being the latest focus - none of which have worked and each took myopic approaches to a very broad problem. I've watched as society became polarized on such arbitrary lines as politics, missing any nuance that may occur across the spectrum; almost turned into a caricature of Star Wars. Home prices are higher than they've ever been, inaccessible to even moderately wealthy citizens.
I may not be on the money with each of my perspectives, though I also don't think I'm really that far off. So riddle me this: Why in the hell would I want to add one more responsibility while dodging and dealing with the bullets of life as-we-know-it today?
