MADISON, Wis. (AP) — The Wisconsin Assembly approved a $3 billion tax break Thursday for Taiwan-based Foxconn Technology Group to build a massive display panel factory in the state, a project President Donald Trump touted as a transformational win for the U.S. economy.

Democratic critics, who don’t have the votes to stop the incentive package or the project, argued that debate should be delayed so the measure could be improved to add more protections for taxpayers, workers and the environment.

Minority Leader Peter Barca, who represents an area near where the plant is expected to be built in southeast Wisconsin close to the Illinois border, said Republicans hadn’t done enough to work with Democrats on improvements.

“Usually if you rush things, FYI, it means the deal stinks,” said Democratic Rep. Gordon Hintz, an opponent of the project who noted that Foxconn has made promises to build factories elsewhere and never followed through.

But Republican Assembly Speaker Robin Vos argued that the project that could employ up to 13,000 workers was an “American field of dreams” that will transform the state’s economy and should not be passed up.

“I care about the future of our state,” Vos said. “We can continue to be naysayers. We can continue to find every fault. We can say, ‘Let’s not take a chance.’ “

The tax breaks would be the largest in state history and the biggest to a foreign company in the U.S.

If built, the plant would be the first outside of Asia for liquid crystal display panels used in television, computers, medicine and other fields.

Republican Gov. Scott Walker, who led negotiations on the deal won by Wisconsin over competition from several other nearby states, has called it a once-in-a-generation opportunity.

The deal signed by Walker and Foxconn officials calls for the electronics giant to invest $10 billion in the state and hire up to 13,000 people at the massive plant that would be spread over a 20 million-square-foot campus. Construction would begin in 2020.

But critics question where enough trained people for the high-tech work at the plant will come from, given that Wisconsin’s unemployment level is 3.1 percent and the state has long suffered from a shortage of skilled workers.

Opponents also point to a wide array of environmental regulations that would be waived under the deal, including the requirement that an environmental impact statement be prepared.

Not all conservatives are on board with the project. The Wisconsin chapter of the conservative group Americans for Prosperity, funded by billionaire brothers Charles and David Koch, came out against the deal as a free market advocate and opponent of government tax incentives.
