Hmmm I suppose my view is strongly biased then. I've lived outside the US most of my life and have always had my own IPv4 address at home.
And sure, as IPv4 addresses are now exhausted, carrier-grade NAT is getting increasingly common. But I would have said the issue started way before that.

Do you happen to have a source here? Because carrier-grade NAT predating mobile networks by decades is news to me.
