The Foxconn's factory plant area is seen under construction at Mount Pleasant of Racine county, Wisconsin, the United States, Nov. 2, 2018. Residents' opposition, labor shortage, and technology transfer difficulties are the three main reasons why manufacturing companies like Foxconn could not move back to the United States easily, industry insiders and analysts have said. Being built on a vast 2,800 acres of land in the U.S. State of Wisconsin, the Foxconn plant project is dubbed by U.S. President Donald Trump as the "eighth wonder of the world" for the scale of investment, the number of new jobs it promises to bring in, and the hundreds of upstream and downstream manufacturing companies that potentially would follow suit. The company, which makes products for Apple, Sony, Microsoft and Nintendo, among others, in 2017 signed a contract with Wisconsin Economic Development Corporation for the display screen plant worth 10 billion U.S. dollars. According to the contract, Foxconn will build a 21.5-million-square-foot (20-square-kilometer) manufacturing campus and hire about 13,000 local workers, and Wisconsin promised to provide an incentive package worth about 4 billion dollars, the largest subsidy offered to a foreign company in U.S. history.
