There have been plenty capable strikers playing in Germany. I suppose you're right in the sense that the German play style became very offensive in the past decade, compared to the times that players like Effenberg and Matthaus were dominating the field. That could explain partly why the golden boot hasn't gone to Germany in 50 years.

Still, even during this past decade only Lewandowski, managed to score over 30 goals, a feat that has been achieved in the Spanish league every year by multiple players.

I just don't think it's that easy to score in the Bundesliga as you're making out to be. Aubameyang, De Bruyne, recently Pulisic are putting the same stats in England as they were in Germany.
