We can't leave everything to the free market. In fact, climate change is, I would argue, the greatest single free-market failure. This is what happens when you don't regulate corporations and you allow them to treat the atmosphere as an open sewer.

I'm not talking about Trump's brand but rather the intimately connected brand called "make America great again" that he created to make all these promises to working Americans - is intensely vulnerable, if there is sustained scrutiny of the kind we've seen about Comey and Russia. He's appointed five Goldman Sachs former executives to his Cabinet, his commerce secretary is renegotiating NAFTA to make it far better for corporations and worse for workers, and they're talking about this right out in the open...

Because it is such a huge crisis, because it puts us on a firm science-based deadline, it's a once-in-a-century opportunity to build a better society and address raging inequality, create huge numbers of jobs, rebuild our public infrastructure. But, we can't do it unless we break every single rule in the free-market playbook. Which is why the worst people in the world all deny climate change.
