Here's a great read about why the Cubs won't win until they tear down Wrigley Field. The real "curse" isn't Billy Goat, but the ball park itself. I always thought it was a dump anyway, offending the sensibilities of certain fans who regarded the place as some sort of shrine. A shrine for losers, if you ask me. Even as a White Sox fan, I occasionally ventured to Wrigley in the 1950s when "loser" was too soft of a name to call the pathetic Cubs. Back then, before Wrigleyville turned into a yuppie enclave, so few people went there that the upper deck was regularly closed.
The Wall Street Journal was sympathetic enough to run a rebuttal.
