The principle of comparative advantage applies even to union picketing

A reader alerts me to this amusing story:

To Protest Hiring of Nonunion Help,

Union Hires Nonunion Pickets

Billy Raye, a 51-year-old unemployed bike courier, is looking for work.

Fortunately for him, the Mid-Atlantic Regional Council of Carpenters is seeking paid demonstrators to march and chant in its current picket line outside the McPherson Building, an office complex here where the council says work is being done with nonunion labor.

"For a lot of our members, it's really difficult to have them come out, either because of parking or something else," explains Vincente Garcia, a union representative who is supervising the picketing.

So instead, the union hires unemployed people at the minimum wage—$8.25 an hour—to walk picket lines. Mr. Raye says he's grateful for the work, even though he's not sure why he's doing it. "I could care less," he says. "I am being paid to march around and sound off."
