Most Americans have never been outside their country and have a limited media created stereotypical view of the world that is laughable to the rest of us.
They'll believe anything the media or government tells them 'cause they simply don't know any better.
I think it's more about the distance one has been away from the place of their birth than leaving one's country. I believe the percentage of people who have been outside of 5000 miles (8000 Km) from their birthplace is low. So they are part of the small media bubble that they've been exposed to. What was eye opening to me, when I lived in countries outside the US, across the Atlantic or across the Pacific, was how much the world followed the events of US government news. In both Europe and Asia, I saw the US president on the news more than I did living in the US. Most news and media around the world is pretty local or regional. Even in the US, the culture and personalities of people are different in different regions. You hear terms like New York hustle, Calfironia cool, Southern charm, Midwest warmth, etc.
When I was in the Army, I could take up 60 days per year, and for my current job, up to 30 days, so I'm luckier than most.
In my earlier years, when I was in the US military, I had 30 days vacation a year. But in the military, they count weekends as a vacation day. Say you get off work on Friday and start vacation and want to come back to work the 2nd Monday. That's 9 days of vacation with the military. Most other jobs, where you don't work weekends, that's 5 days of vacation time. I found that a bit deceitful about vacation while in the military. Being young at that time, vacation was just a desire to get back home where I grew up. Different from vacation as an older adult.
When you say you get 30 days now, is that 6 weeks a year, 240 hours? That's really good!
In my industry, lots of companies have gone to unlimited PTO (Paid Time Off). That sounds good on paper but people feel guilty about taking time off, so the opposite of getting more days has happened. Or there's more work than one can do in a day anyway and companies say, you can take time off as long as you get your work done. But if work is never able to get done, then you can't afford to take vacation. Then when you leave the company, you have no vacation days on the books which the company has to pay when you leave.
"... have a limited media created stereotypical view of the world..."
Thats exactly what many germans think about US-citizen and what they are not aware of is, that their own view of americans is the same way a stereotypical view. Most of them don`t know a single US-citizen personally but they have a strong opinion about them.
This really makes me wonder how much of the media in any country is directed by its government. Or if not by the government of that country, by a very few very rich who own the media? About the statement of people not knowing a single person from a different country, hopefully the Internet and sites like this help one person at a time to realize all humans around the world are similar.
