I dunno- I have been to Florida many times, and I think it would be a lousy place to manufacture. There is basically NO industrial infrastructure- hardly any suppliers, hardly any heat treaters or polishing shops or galvanizers or machine shops for subcontracting.
Everything would need to be either done in house, or shipped for a couple of days each way.
Most any material beyond simple A36 round bar would need to be special ordered.
Employees would be cheap, sure, but in experienced- very few machine shops, or manufacturers, not good community colleges with machining or manufacturing programs.
If you needed a big industrial circuit breaker, or a CNC machine repairman, or a part for your huge parts washer, or a certain grit wheel for your surface grinder- forget it- mail order only, usually.
So any minor breakdown could mean days of lost work time.
Versus CT- with a couple of hundred years accumulation of industry, everything you need is a few hours away at most.
I personally have found that hiring cheap employees is usually not a savings, but a cost- if you dont have good guys, who know what they are doing, it costs a lot more to make things. And Florida is the drain of the USA- all the hairballs, grit, debris and toenail clippings are circling around.
Not to say I dont like Florida- I do- but I sure wouldnt move a factory there...
