Looking for a job?

I once heard that the Chinese government employs far too many people. On the way to school one day, I saw a sidewalk-cleaning expedition underway. Don’t forget that these sidewalks are so filthy that no amount of work will ever scrub them clean. Regardless, there were several people sprinkling dry soap on the sidewalk, several more following them with water, and many more after that (five minimum) with big brushes, hard at work scrubbing that sidewalk. On top of that, there were people in the street with big brooms, pushing the suds that escaped into the gutter. How many people does it take to clean a sidewalk? (Insert corny punch-line here.)
