Redux

The lack of an "off-season" is a big reason for it being a problem.  He addresses the year round schedule next.  This was very true a decade ago.  Today not as much.  With 2 major brands (RAW and Smackdown) and 3 minor brands (NXT, NXT UK, and 205 Live) they are able to churn out live weekly content featuring different rosters without multiple house shows being such a major factor.  House shows are the equivalent to a spring practice and they used to do them untelivised 3 or 4 times a week with the same roster.  Now it's split up quite a bit.

Starting to touch on the unsafe environment.  Okay, stepping in the time machine a bit:

In the 80's the steroid stuff was obvious.  Those guys pushed their bodies to insane limits.  Why they are dying off, that's obvious.  The 90's saw a lot of wrestlers on the trucker method of keeping their momentum going.  Again, obvious why they are dying off.  Is it their fault or the companies? Well it's both really.  As stated, you miss work you lose your spot.  They say this like it's a bad thing but the same is true literally anywhere there is someone waiting on the bench.  The show must go on and plenty of talent is ready to step up and often times does.

CM Punk is about the worst person to ask today about Vince and the WWE.  He is a massive prima dona and was a notoriously difficult person to work with because of it.  Talented as he was, he always wanted more and demanded it.  They essentially fired him on his wedding day because of a contractual loophole.  Being an a$$ will get you treated like one.

And of course Vince does these things to keep his minions churning out production.  What leader of a billion dollar company doesn't?  I'm not saying it's right, but mostly all of them understand what they are getting themselves into.  

Starting on the concussion stuff.  Yes they no longer allow chairshots to the head, the piledriver is basically not allowed anymore, and many wrestlers were forced into early retirement like Daniel Bryan, Edge and Paige because they would no longer clear them for in ring competition.  Yes Daniel Bryan finally got cleared but I expect it to not last much longer honestly.  So the horror story like CM Punk describes them "forcing" him ignores the fact that these people WANT to compete.  It's their lifeblood.  Not wrestling is a major withdrawal when you want to.  Ask any of them...besides CM Punk whose too busy embarrassing himself in MMA.
