Alt text: Chart showing average height, but incorrectly scales the entire person instead of just the height, with the Netherlands as the tallest and Indonesians as the shortest. Bottom image is the Bane vs. Pink guy meme showing Bane as the Dutch and Pink guy as the Indonesians.
Considering that the Dutch were below average before the second world war, I think your hypothesis is wrong. I think they were just compensating for being tiny during that time.
On a more serious note, I just think the Dutch had zero scruples (inventors of modern capitalism and all).
They just didn’t care how many people they screwed over aslong as they could get one more Gulden in their pocket.
