Their only mistake was assuming money would be enough to attract business to relocate to Kansas.
the only mistake was the entire plan?
I pay less in taxes, even after the tax cuts were scaled back, so the plan got that part right. Kansas's primary hindrance to attracting new businesses remains unchanged: when the weather isn't dangerous and/or a pain in the ass, it's rough ridin' boring. No mountains, no beaches, no pro sports teams in the vicinity except for the very NE corner, etc. So you maximize the advantages you have: low taxes, low regulation, low cost of living, cheap land, etc.
For all the libtarded blather about education funding, medicaid expansion, and all the other things they'd love to tax and spend more of our money on, that's not going to drive business to our state. The few liberal-run businesses that might care about that crap aren't leaving the coasts/mountains anyway.
