I think I could make the case for a class action against the government for inflation.

After that, I'll file a case against the entire practice of currency trading because the value of my dollar bills are being devalued by some currency trader somewhere.

While we're at it, shouldn't sales be illegal? If it's illegal to raise the cost, why isn't it illegal to lower costs. We should go the German route and prohibit stores from having sales which discount things below cost. That means all those web fares are illegal.
