What does the Wild Card do for Baseball?

Baseball has a shorter playoff than any other sport with less teams also. They also have a longer season. Some people question what the expanded playoffs and allowing the Wild Card in has done to baseball. In the past 5 years the Wild card, the team who wasn't good enough to win their division has made it to the World Series. People question why a team who didn't prove themselves in the 162 game season can then have a second chance for redemption in the playoffs. Owners have came to an agreement that letting them in is a good thing for simply one reason. More money. More teams in the race for the pennant is more ticket sales and gives them more money. Now the question is that do we feel that baseball is tainted now by owners wanting more money and letting some teams that may not deserve to be in the World Series be there rather than another team who proved themselves over 162 games, or is it fair to let second place have a chance at something that first place worked so hard for?
