The court has a history of saying "Hey voters -- you asked for this, you fix it." This opinion is simply the court's way of saying "If you don't like taxes, don't vote for politicians who raise your taxes." Roberts drew a very clear line. He said the federal government has the power to tax any group of people it wants in order to incentivize them one way or another. Ok... so now our quest is clear... if we don't like this power of government, we have to limit (re-limit) government via a constitutional amendment.
