You blame a lot of people who make decent salaries, but put none on your employer, your local government, your states, or anything else. There's a plethora of things your own government could do to help out. Why blame the people who obviously left the west coast due to cost of living (the same thing you're complaining about), and not blame the system and people who allowed it to happen in the first place?
Adding on the whole literally calling them "refugees" like they're leaving some barron hellscape behind while literally just exposing the same problems in capitalism as a whole. Just because you were isolated from these problems before doesn't mean they didn't exist.
I just don't get it. You claim to be left leaning and working class - but the second these issues we fight for literally start affecting you you don't like them anymore? What do you think we've been fighting for this whole time. The ironic thing is that those who probably moved in are probably more left leaning and in more of support for policies which your politicians refuse to enact. (Higher taxes for higher earners, more safety nets, rent control, etc)
Blame the system that allows it in the first place and those who uphold that system. Blaming them just comes off as pure envy to me.
