The price of transitioning from a dollar store economy to a more worker-driven system (if it can be accomplished, which is very questionable at this point) is likely to be lower share prices and higher consumer prices. The price of moving quickly from fossil fuels to completely clean energy will be intermittent shortages of electricity and higher energy costs. The ultimate benefits of these systemic changes will exceed the costs, but it would be a mistake to behave as if the costs do not exist.
So far, I have seen no evidence that any Democratic leader is willing to level with the American people on these matters. The electorate is responding by complaining about rising prices for gas and consumer goods. There will be problems at the polls if the party doesn’t develop a more sophisticated message between now and 2022.
