It's working so well for Kansas, so well. 

"Since it took effect in January 2013, total employment in Kansas has risen only 2.6 percent, compared to 6.5 percent nationally. Private sector employment in Kansas has risen 3.5 percent, compared to 7.6 percent nationally.

The state’s economy has grown less than half as fast as the national economy; Kansas’ gross domestic product (GDP) grew 4.8 percent from the end of 2012 through the first quarter of 2016, while national GDP rose 11.9 percent.

Kansas’ share of newly opened business establishments in the United States has actually declined slightly rather than increased."
