I find the proposed elimination of the rule requiring advertisement of the full price to be odd. Wouldn’t an honest Republican administration be in favor of price transparency as a measure that increases the efficiency of the free market?
Sure, but not enforced by the federal government. The theory is that the free market will take care of everything. If the market values price transparency, then companies that don't practice it will lose to those that do.
Of course, appealing as this theory it, the evidence is overwhelming that it doesn't actually work. But the Republicans have never been keen on letting data interfere with ideology.
Lots of people think that the fees and taxes should be made clear so that people are aware that they are paying them, but there's no reason that can't be done in addition to showing the actual cost of purchasing a given ticket.
