Yes, I do think so. It's funny because I am living in a very oil and gas rich gulf state that on the one hand is very sophisticated - the elite families/clans are all highly educated, worldly etc, and yet because the country is still very new in terms of development and infrastructure I find that many, many aspects of their culture are again very similar to what we would expect from gypsy and traveller cultures back home. I suppose it comes from being descended (not very many generations ago) from bedouin tribespeople - feudal, insular, patriarchal, always on the move, etc.
For example, despite the fact that they are obsessed with mobile phones, even now they do not like to communicate through email, and they won't be governed by the clock or the calendar - the way to get business done is in the here and now, face to face, spoken not written, when the fancy takes them and not necessarily when you thought you had scheduled an appointment. They have no concept of having inconvenienced anyone by being this way. Their children have a terrible school attendence record - if they fancy staying off school or work for a few days or weeks on a whim, they just do it! No explanation, no apologies. They are beholden to no-one.
The other things are a completely cavalier attitude to things like driving safety - I've yet to see a single non-Western toddler or child in a car seat out here. they just scramble all over the car like it's a ball pond. and literally sit on the dashboard quite often. And the death rate among local youths and young men on the roads is absolutely appalling. just like with Travellers. But they put their safety in the hands of God and fate. Which would be fine, but as they drive like total lunatics God really has his work cut out. 
And the habit of making your home like a ostentatious palace, all gold and sparkly and new and shiny on the inside, but then the area immediately outside your gate is a rubbish tip. I am starting to realise that this is typical of cultures where traditionally they would always be packing up and moving on. Keep the stuff you carry with you tidy and clean, and let someone else worry about what you don't want/need. Fine when all you were leaving behind was some human waste, some scraps of firewood and a cooked goat carcass in the middle of the desert or the forest (in the case of gypsies in Europe) but these days, not so good....
Anyway - I digress. Sorry, back to the Amish. But my point was about how/when these insular cultures and communities are suddenly made to collide with the rest of us, and how there is a clash of values/expectations.
