Your problem isn't Massachusetts (other than maybe the gun stuff), it's living in a shitty part of Mass. I've lived in central MA and it doesn't feel all that fundamentally different in NH after being here a few years. Almost all of the benefit of lower income taxes have been erased by ridiculous property taxes. If you are going to have kids, you'll still have worse schools unless you live in towns with truly insane property tax on top of extremely high priced real estate. Any place within striking distance to Boston will be as expensive, if not more, than similar commutes within MA. The job market doesn't even come close to comparing.

The trick is to actively seek out a role that has growth possibilities that are fully remote, assuming you can't find something fully remote that is available now. If you get your foot in the door in a place in Boston, or Newton, or Framingham, or the 10 other places within MA that all have viable tech sectors, then you can parlay that into a fully remote position and go wherever you want and not pay state income tax; you get the benefit of the MA job market with the eventual other benefits of NH down the road.

I guess you have no choice but to follow the jobs at this point if you can't find something in NH.
