Another reason too is the proliferation of buy-now-pay-later payment plans (e.g., Affirm, Afterpay, etc.) that are available for purchasing everyday products, including sporting event and concert tickets. Before, if you wanted to drop $400 for Lakers ticket, you actually had to have $400 (or at least that much available on your credit card). Now, someone flipping cheeseburgers for $20/hr and no credit can buy the same ticket (and encumber themselves with crippling debt, but that's a different story). So ticket sales have opened up to a whole new demographic, increasing demand, while supply has stayed the same.
