The obvious & easy answer is that these festivals bring in revenue. It helps keep the tourist industry running. If politicians are not even remotely interested in protecting the urban boundary development line from being pushed further & further out (swallowing the Everglades & destroying our drinking water) why would anyone assume they cared about the mounds of trash thrown into the bay, ocean, & streets? Politicians care about money...PERIOD! If the trash were to effect the amount of tourist then it would be a priority to clean it up. What I find interesting is the "city-led bidding process..." This is Miami, where the bidding process is just as fraudulent as the people running this state.
