From jump-the-queue passes in theme parks to paid-for express lanes on roads, the US embraces a free market philosophy that the last shall be first and the first shall be last.

Money has always purchased privilege and priority. Bupa gets you to the top of the cancer treatment list. An Eton education may fast-track you into the Cabinet. When you're standing in a packed train, those empty seats in the other carriage are called first class for a reason.
