All-Star Games

Can someone please explain to me why professional sports still have All-Star Games?  Seriously, I don't understand the reasoning behind having them anymore when the only one I watch is the MLB All-Star Game and that is because it airs in the middle of the summer when absolutely nothing else is on TV except Two and a Half Men reruns (then again, if you like fart jokes then we all know what you are watching that night).  Each major sports' All-Star Game is heavily flawed, so let's break it down:

• NFL Pro-Bowl:  It used to come on after the season was finished, but now its held the week before the Super Bowl (however, I think I heard it is now played after the Super Bowl again, so confusing), therefore, every player picked to play in it from the Super Bowl teams are automatically out.  That means that a handful of the best players from the best teams are already going to miss it.  On top of that, since none of the players want to get hurt while playing in the Pro Bowl, they either don't play hard or skip it altogether meaning even crappier players are substituted in their place making the game even worse.
• NBA All-Star Game:  No Defense.  Neither team gives a damn about playing defense which may seem cool because the final score is super high, but it also sets up way too many easy points which defeats the purpose.  Also, the Slam Dunk Contest usually overshadows the actual All-Star Game, but since no one even knows who those participants are anymore, no one cares about that thing either.
• MLB All-Star Game:  This one is stupid for a multitude of reasons.  First, the ballots are released a month after the season starts, therefore, only a small percentage of the games have even been played and no one can really gauge who should be picked.  Second, the fans pick the starters for each squad meaning that the teams in larger markets with the biggest fan bases will always get their players picked over more deserving players (which is why the AL roster is always loaded with Yankee and Red Sox players, but so far this season, the Texas Rangers are owning the starting spots).  Third, the coaches from each team are supposed to make sure that every player from their respective teams gets some playing time, therefore, the end of the game is always littered with the bottom of the barrel of the All-Stars in the game.  Which brings us to the last reason that this game is so stupid - the winner of the game gets home field advantage in the World Series for their league.  So, this means that the worst of the All-Star players are ultimately going to decide who gets home field advantage in the World Series because the coaches have to play everyone who was picked.  That's just stupid.
• NASCAR All-Star Race:  Yes, I'm including this one because it is as equally stupid as the other ones on this list.  First off, the All-Star Race is held two months into the nine-month season.  What?  On top of that, what exactly constitutes an All-Star in NASCAR?  Because Dale Earnhardt Jr was in this year's race and he hasn't even won a race since 2008.  Lastly, how can you have an All-Star Race when the guys competing in it will just be competing against the same guys in every other race the rest of the season (minus the scrubs)?  Nothing about this race makes any damned sense.
• NHL All-Star Game:  This is the only game that I think has a really cool element to it.  First, the fans and players pick who is going to compete in the.....match (is that right?).  Then, two captains are chosen who then alternate picks to see who will play on the two teams.  How cool is that?  Too bad it is hockey and no one gives two shits about that sport other than Canadians.
