The Week (and, earlier, the N.Y. Post) reports a new way for high-wage people to economize on time: when visiting Disney World, hire a “tour concierge” — a disabled person who uses his/her disability privileges to ignore waiting lines (and take the high-wage person and family with him/her ahead of the crowd). At $130 per hour, the time saving is easily justified economically (just think of the lines at Space Mountain, or at my personal favorite, Small World). It would be nice too if people would rent me their toddlers to board Southwest Airlines flights ahead of the mob. Clearly, there is room for beneficial exchange like this in many areas.
These are not, however, Pareto improvements: while the “concierge” and his/her customers gain, everybody else in line loses. It doesn’t seem fair to me, and perhaps not efficient, since the externalities of extra waiting time for the whole line can be substantial.
