The VP of Eng at my current job routinely takes a week off where he is utterly unreachable (I believe he literally went to amish country last time). The same applies to the rest of the engineering team. It's been the same at my previous two companies as well. No, it's not the norm at companies but there's plenty where that's the case.
In my experience, the US is a place where little is given to you but you can get a lot. But you cannot take anything for granted. If you value vacation then you need to grill potential employers on that point and be willing to take a job that pays less. Most people value money so if you value something different you need to be proactive about getting it.
You make a great point and one thing I posted a bit further down was when I was a director level I did a really poor job of leading by example when it came to vacation. I would literally force people to use their pto and I didn't and they would feel weird or bad. I should have been more like your VP.
