Plenty of non-tea-drinking countries have kettles pretty much ubiquitously. It's mostly just North America that doesn't have them because the advantage over a stovetop kettle is greatly reduced due to only getting 1500W (rather than 3000W) out of the plugs.

Of course... I solved that for myself by putting a NEMA 6-20R in my kitchen and importing a 3 kW kettle.
