Slate magazine caters to the crowd who think that society would be more fair if we each lived at the expense of everyone else, and that everyone must obey our wise overlords. If our wise overlords think you will be more healthy if your house is kept at 50 degrees in the winter, that is what everyone will have. If you disagree, then government won’t pay for your health care like they promised they would.
This feels like a propaganda piece. Turn down the thermostat - it is good for you and the planet!
