Also the average salary in [Western European country] is $6,600 a year? I'm not sure I believe you...
Either I did my math wrong or you're looking at the promotional price, only valid for six months. The WSJ costs $37/month, so 37x3x10 = $1110, or about 901€/month. Our average base salary in 2016 was 925€/month.
A digital subscription is half that, and the salary you're quoting is well below the poverty line which makes me suspicious it's not really an average or it's a cherry picked example.
Clearly the WSJ must be A/B testing, because the price I quote is what it shows to me: http://sufi.andreparames.com/wsj.png Are you sure you're not just looking at the promotional time-limited discount? Because yes, that's half that. But it only lasts a few months.
As for the average salary, I do have to say it's after taxes (I didn't write "gross", but "base" might have been misleading, though it's how it's called here). The gross is 1154€/month. Yes, it's fucking low. This is why we emigrate a lot.
Subscribing to just three newspapers at those prices would represent 10% of the average salary in my Western European country.
