North/Central America is kind of the outlier running on 100-ish volts. Most of the rest of the world runs on 200-ish[0]. Electricity-related deaths aren't exactly common worldwide. And yes, I can see 100ish causing more fires — given dissipated power scales with current squared, my 2kW tea kettle can't possibly be safe in the US.
