Yes, but these are averages so it shouldn't matter. Assuming this is total spent in all households over a year, divided by population, it accounts for all fluctuations in time and region. And at the end of the day, all that really matters is what you paid over the year.

And they already have a chart that adjusts for average wages as well.

So nothing whatsoever here strikes me as misleading or propaganda. Averages are a totally legitimate comparison tool between countries.

I'm actually curious just what you imagine this could even be "propaganda" for. Because it seems like just an incredibly fact-based neutral overview to me. I don't see any agenda at all, unless there's a sentence or paragraph I missed?
