From  New America Media: Twenty-four year-old Karla Mi Lugo has been street performing for four years. Up and down the West Coast and San Francisco is her current stage.  Street performing is Mi Lugo’s main source of income. She says 40 bucks a day is good enough for her. Mi Lugo is part of the growing underground economy, a market where service is given without contracts or receipts and the term “under the table” is the password.
