When I was living in California I used to see some fancily dressed Vietnamese couples shop at food stores and pay with food stamps (government welfare). The cashier and I just shook our heads at eachother. Welfare systems are there as a temporary help for people, and not as a work supplement. In the USA, Germany, etc. you hear stories all the time about immigrants, more so than natives, who abuse the system. Since many come from countries that give them nothing, why not take advantage of it. I usually find these people stay at the bottom of the economic scale most of the time. It's karma for taking advantage of the system.
In terms of going overseas, I hear my students here all the time tell me that Chinese people are treated very badly abroad. But if you ask them if they would want to leave China, most would leave. One hundred years ago Chinese people were treated bad, not not anymore. The complexity of China once more at work.
