Politicians love cap and trade because they can claim to be taxing "polluters," not workers. Hardly. Once the government creates a scarce new commodity -- in this case the right to emit carbon -- and then mandates that businesses buy it, the costs would inevitably be passed on to all consumers in the form of higher prices. Stating the obvious, Peter Orszag -- now Mr. Obama's budget director -- told Congress last year that "Those price increases are essential to the success of a cap-and-trade program."
Hit hardest would be the "95% of working families" Mr. Obama keeps mentioning, usually omitting that his no-new-taxes pledge comes with the caveat "unless you use energy." Putting a price on carbon is regressive by definition because poor and middle-income households spend more of their paychecks on things like gas to drive to work, groceries or home heating.
