That's not an unfair assessment, but I would pose additional questions:
Why does doing the morally sound thing always have to be easier, better, and cheaper than ruining the world and creating human misery? Why must the morally superior argument be financially unassailable?
I'm getting older and angrier and I've grown tired of meeting greedy, disingenuous adversaries halfway just to have my hand slapped away after they get what they want. Since we've established that conservatives will absolutely put up with pain to harm outgroup bogeymen, I don't listen to their appeals for things that I hope will reduce human misery in the world.
With that in mind: Tax the rich like it's the 1950s, healthcare for all, stop burning fossil fuels, etc. Do it all and see what works, darn it.
