No it was not "monumental buildings". These were very average buildings I'm talking about. In fact I saw two related buildings, only one of which was permitted to have A/C (and an awful portable one at that), as the locals told me. Everyone complained about it.
Be glad where you live isn't like this, but this is not universal.
> Also, every single hotel and commercial place has it.
I can't speak for your city or the Netherlands but this is absolutely not even remotely true universally in Europe. Most places I found (yes that includes nice hotels, yes in multiple countries) lacked A/C, and even the ones that had something they called "air conditioning" on the booking websites vehemently rejected the notion that they have A/C when you asked them in person -- in their own eyes it wasn't proper A/C, and I agreed with them after trying it.

But really in the netherlands which this article is about it should not be a barrier. The weather there in summer is extremely variable. Yes you get some hot days but they are few. And like I said, if you really want AC you are free to pick a place that has it. If you're a skilled migrant you will be well compensated anyway. You will have your pick. Viewing that as a barrier is just blowing things out of proportion.
The same way that American media is these days talking about Europe like it's overrun with migrants, it's just political.
