USA needs to learn from Singapore. There are 3.5 million citizens and 2 million foreign workers in Singapore. Foreign workers get 2 year work visa’s, and they are very happy to obey laws because of the job benefits. They do not receive Singapore citizenship based on work visa.
Result is a very prosperous country of Singapore where every 6th citizen is a millionaire.
From 1 September 2012 only foreign workers with earnings of at least S$4,000 ($3,150) per month can sponsor their spouses and children for their stay in Singapore and some of them are also not allowed to bring their parents and in-laws on long-term visit passes.
The influx of immigrants and foreign workers to Singapore has resulted in strong sentiment by the locals against both the foreigners and the government, and was a major issue in both the 2011 general and presidential elections. Singaporeans have attributed to the government's open-door immigration policy the country's overcrowding and falling reliability of its public transportation system, increasing property prices for housing, suppressed wage level, increased competition for jobs and education, increasing income inequality and other social problems. These issues came under close scrutiny by foreign media in the aftermath of the 2013 Little India riot.
New salary rules were adopted in 2013:
Firms looking to hire foreigners must now pay their full-time local workers at least $1,000 a month.
With effect from 2014, the Employment Act will cover non-manual workers earning up to $2,500, making them eligible for over-time pay. 150,000 workers are expected to benefit from this change. Previously, only non-workmen earning up to $2,000 qualified.
Tan said that to help employers manage their costs, the amount of over-time payable will be capped at a salary level of $2,250, meaning that workers earning between $2,250 to $2,500 would get the same over-time rate of $17.70 per hour.
I would also add that Singapore has the lowest fertility rate in the world—.8 compared to our 2.01.
