That Gilens and Page study has been debunked time and time again by various followup studies. Overwhelmingly the American people get their way. If not that, just look at direct polls from sources like Gallup. Even amongst climate-conscious progressives, the will to pay extra for gas or beef to negate climate change just isn't there.

Edit: as a test question for anyone who believes this 90% nonsense - can you name a single piece of high-priority, salient legislation (i.e. not an executive order or Supreme Court decision) that a vast majority of Americans didn't want, but that went through anyway because the government did the bidding of the corporations?

Overwhelmingly, the reason why we don't get policies like climate change mitigation, universal healthcare, housing, etc. is because Americans are just fundamentally divided on these topics. And where they are somewhat "united" (say, a public option for healthcare), they don't want to increase taxes to pay for it.

(High-priority and salient because things like dairy trade policy are probably influenced more by lobbying, but that's because most Americans obviously don't care about dairy trade policy)
