As a consequence of the higher voltage, the current is lower for the same power and where I hear a lot about electrical fires in the USA, that is a rarity in Europe, while here in the USA I personally know of two people who had a starting electrical fire in a power strip, one could barely keep the flames from setting the bedroom on fire.
Going back to GFCI: my garage has a GFCI circuit. As a consequence, I cannot use my garage to do any development work, because as soon as I plug in one of my HP power supplies, even before I turn it on, the heavy capacitive filtering on the AC line will trip the GFCI because it indeed creates a current to ground. Though it is not leakage, it is actually intentional because this is how you squelch EMC emissions on the power line. And how you trip the GFCI. I need to run an extension cord from a non-GFCI circuit to avoid that the lab power supply trips the GFCI, talk about nuisance trips! If I am not mistaken, the NEC has a class of GFCI (and I used to have a breaker) that trips at 50mA, I believe there is even a 500mA limit. This is only used in industrial settings where a lower limit will indeed trip guaranteed.
