If the US had the same IPv4 scarcity as the rest of the world (specifically, if major US ISPs were using CGNAT), the IPv6 transition would be happening much faster.

The addresses were allocated equally geographically, and then sold. The US will hit ipv4 scarcity when the US stops being the richest country.

Prior to the establishment of the RIRs (Regional Internet Registries) the IANA handled IPv4 allocations directly and without regard for geography. During that time most of the early adopters with US government, US Universities, and US Corporations. Several US Universities and Corporations (for easy examples, GE and MIT) simply asked early enough for IP addresses and got entire /8 allocations.

Sure, when the RIRs were built they were assigned roughly equal shares of the remainder of IPv4 space, but it certainly failed to account for those early years of early adopter allocations, which did accidentally favor the US heavily.
