Can someone explain what's behind this phenomenon? Who owns the supermarkets, how do these immigrants afford their travel, do they have to work a certain amount of hours to pay back loans. What kind of visa do they have, some govt special? The Chinese workers I've chatted to have to work at least 14 hours a day, 6.5 to 7 days a week, 363 days a year. I've heard lots of stories, can anyone enlighten me? Thanks!
