Could go into that? IIRC, 110V is less efficient but it's also less dangerous, so maybe it's more of a trade-off.

But your point stands. I've read that the reason Estonia's government infrastructure is so much more advanced than the US's is because they had visionary leaders and started from scratch in the 90s. The US has the weight of decades of good-enough paper processes weighing it down.

Ya, I miss the satisfying "pop" I get when plugging in to outlets in China without a ground pin.
