Based on research financial backer and owner of the promotion Tony Khan is currently worth 4.5 million dollars and his father Shahid Khan is worth 6.8 billion. Now I don't think his father has anything to do with the promotion, but it is possible that his family could help similarly to Panda Energy & TNA Wrestling. Either way though Tony has even put on record that he would treat his new employees as actual employees which would mean he would provide to them the same connections that most employees do.
Overall there isn't much known at this point about this aspect of what the promotion could provide, but I do think that this would help draw some talent to AEW. In my opinion it would help benefit the wrestlers take a step forward, but I do think it could hurt the smaller promotions due to the added expense of the union fees. However, hitting the mark with this would be if the AEW does make the move to set up health insurance for some of the workers it will be interesting to see where this goes and if they can actually set up something that has really never even come close to becoming a reality.
