My husband is also Swiss and, although he really likes it here, he finds the littering disturbing.My fiance is swiss ...
I think the difference between Switzerland and here is that the people there are self-policing. For example, they have strict laws on dogs soiling pavements and green areas. You have to pick up your dog's poo or face the possibility of a fine and the wrath of anyone who sees you walking away from it. My father-in-law has no qualms about berating people who litter or fail to clear away the dog mess. Would I do it here? No. I'd be too afraid of the consequences.
We decided to stop travelling 7 years ago and had the choice of living in Switzerland or here. We chose Ireland and, despite the shortcomings, we both feel we made the right choice for our family. We're hoping to eventually retire to Switzerland - mainly because of the weather and the high standard of health care on offer.
