What goals are so terrifying to them? I honestly don't understand that what so ever.
Other than fear of the other person (thanks for reminding us, drew) what policy is so very damaging to this country?
Clean air and environment? Healthcare for everyone? Worker protections that end up raising wages? Seriously, what is so wrong?
The only people who would "suffer" are the very wealthy because they will actually have to pay their fair share of taxes. And even then, they will have more than enough money to live ultra comfortably.
The only people I can think of who will really suffer are the coal miners (who are already suffering- they were replaced with machines 50 years ago AND the next group have made their coal worth less) and the oil drillers. And even them- it's a very transient job already thanks to forces outside of this country. And NG is going to last longer than diesel, thanks to it's less impact on CO2 for what it does (ships are transitioning to CNG instead of bunker fuel).
And for those impacted, they can do what their parents did- move someplace where jobs are. Green manufacturing is a real thing.
