It's all about stadiums and quality of the facilities. Harry Grove isn't up to snuff as much compared to Bowie or Norfolk. Also the reason why Hagerstown will go way of the dodo as well. It would cost a fortune that Frederick City or County would never pay to upgrade Harry Grove to meet the standard, or whoever has to pick up that tab in the lease agreement. That and Frederick doesn't make any $ because Ziedelis just tells Ken Young what he wants to hear and is a total kissass while the team loses $ every year. Same with Bowie but bowie has a better stadium in terms of being on par with MLB's requirements. The whole "PAY THE MINOR LEAGUERS" campaign was going to resolve in teams being cut because MLB profits would be effected in a big scale and how shrewd MLB is with costs and revenue historically. I called this a year ago in a baseball discord server and it sucks that I'm right. A "livable wage" (if one exists) would only be paid to minor leaguers if teams were cut in predominantly rust belt, more expensive or poorer areas with lacking facilities, and look where we are. Hopefully a resolution passes and hopefully MiLB and MLB will solve this and keep everyone happy, but I highly doubt that happens. As someone who grew up at Harry Grove as a kid, that's going to really suck seeing the keys fold or go to an independent league. Such is the nature of the beast I suppose.
What'll be interesting I suppose is to see how Manfred looks and acts during this debate because apparently the players and owners might go in for extended talks come 2021 when the CBA expires. This is going to show the players how much they can push against this current Commisioner versus what they could push for with Selig. With that being said, it's looking like Manfred will be going in guns blazing and just wanting his way. The thought that lower minor league teams will have to scout and develop their own talent like they did almost 100 years ago proves how cyclical history is.
For further reading, here's a baseball America article going into detail on what we could be seeing, how the agreement with MiLB works, etc. I have work in the morning and need sleep. https://www.baseballamerica.com/stories/mlb-threat-pushes-negotiations-with-milb-to-another-level/
