I’m going to guess you’re in the States? I’m from England and live in the Netherlands. I’ve never met anybody ever who didn’t own a kettle. Is it true that it’s really not that common in the States to own a kettle?
I would say 20 years ago almost no one had an electric kettle in the US. Now they are much more common, but still only in a minority of homes. Americans just don’t drink nearly as much tea as the English. The UK consumes 1.94kg of tea per person annually. The US is 0.23kg. (per wikipedia). You will find a coffee maker in most homes and hotel rooms though.
