Pros
It reliably pays you a wage.
Cons
I personally sat in on meetings in which upper management emphasised the importance of encouraging scalpers, encouraging resale of tickets from within the company, and proposing specific engineering of ticket sales platforms to prioritise the advertisement of resale tickets. Towards the end of my time in this role, managementn suggested theaters and acts who allow/ use the resale feature to receive extra kickback, above and beyond the profit they would make from resales. The transfer of these funds to the venues and acts was presented shadily and were often called "preferred" entities due to the personal benefits Ticketmaster would receive.
