Anyway, Occupy Wall Street reminds me of another current phenomenon, food trucks and other businesses that have set themselves up rent-free in the public streets.
For example, in recent years, there's always a big yellow sign advertising "Thai Massages" (I presume that's a euphemism) mounted on a trailer parked in the right hand turn lane at a busy nearby corner. It's a great location for advertising a massage parlor because the pimp doesn't have to rent the land the sign occupies. Less obnoxiously, there's now often a miniature barber shop in a trailer parked in front of a prosperous local strip mall where monthly rents are substantial.
Similarly, downtown Manhattan is, for most people, one of the most expensive places in the world to live, but a couple of hundred people have been camping rent free there for two months.
Why this 200-person free campout is the biggest deal since the Fall of the Bastille, however, is another question entirely.
