Yup, that's all true. Although we've debated the merits of licensing here many times before, licensing in New England does prevent an out of state contractor from blowing into town and hiring day laborers for help.
And guess what? If an out of state electrician is jobless, he'll be in the testing center as fast as he can get there to get a Connecticut license so he can start working.
Or maybe be working then go to the testing center, If I were out of work NOTHING would stop me from pursuing a job, licensing is only a matter of paper work if you are qualified.
