Why does Ulfric not target the successful Altmer merchants in Windhelm?

So I was having a very… special… conversation about how racist Ulfric is, which lead my down a uesp dive to elvauate it for myself based on what is actually presented in game.

so yeah he’s pretty racist, not as racist as the Average Redditor thinks he is, only a middleweight in the Tamrielic Competetive Racism League.

But something that was odd to me is that there are several successful Altmer business owners in Windhelm’s economy. Niranye, Ulundil, Nurelion. Surely Ulfric’s ideology and experience with the dominion give him more of a reason to hate Altmer even more than he hates Dunmer and Argonians. And it is common for racist regimes to try to bring down the businesses of target minorities. But the Altmer never say they have a problem with Ulfric, and he never brings up how many Altmer are in his city.

This is just a weird thing to me that the writers didn’t do anything with this.
