I agree. Not only the "unfriendly political atmosphere", but in this day and age the astronomical cost of utilities to heat large manufacturing plants for 6-7 months each year must be staggering. Not only are states in the NE "gun-unfriendly", but they are also "energy-unfriendly". So not only do you need more utilities, you have to pay some of the highest prices in the US to get them ! And high energy prices lead to high salary prices. Salaries are 10-20% higher there too.
Anyone who thinks CZ is "moving from KS to CT" is drinking the rumor mill Kool-Aide. The army of CZ accountants will make sure that never happens. Oh, they may say that to soothe certain local politicians or meet contractual time limits set by unions, but the writing is on the wall... in 10 foot high letters !
