How long have we waited for global, single standard for electrical outlets and associated power grids?
Well, a single standard might be a bit much to ask because of the infrastructure investment in 230/120.
Consolidation of plugs within service is underway, especially in Europe where (since plugs and outlets were and are considered to be national matters) the high density of countries per square km makes this problem a lot more noticeable than here.
As for 120 service, IEC 60906-2 codified the supremacy of the (inferior) NEMA5-15. (at least it's better than unpolarized NEMA1, but I could really go for insulated pins and firmer connections so I don't have to worry about shorting across the pins when something inevitably falls halfway out of a socket)
