Where I come from, people(even skilled people with university degrees) work 9 hours a day for ~330-400 NZD a month on average, and I'm looking for an escape from it. I don't mind working 24/7 as long as I get a fair treatment in terms of salary and stuff. I wouldn't dare ask for any benefits, let alone sit around without an employment and complain about it, it'd just be plain disrespectful to my new homeland.
I'm sorry to read that you've encountered something like that, but I guess we're bound to bump across some odd people anywhere in the world. "I'm a respectable law-abiding resident, pay my taxes and I'm healthy. ", that's what I abide by, and I agree with you 100%.
In small places over here we got the same social customs; always say "good day" to a random pedestrian, just to avoid any uncomfortable situations.
