This nails the core of the problem. Ride capacity is not keeping up with attendance. You can come up with various systems to let some people skip some lines some of the time, but the bottom line is that, if you have too many people and too few things to do, most people are going to be standing in long lines most of the time. No amount of rearranging the deck chairs is going to change that.
Disney's decisions even before Covid to cut back on entertainment and to run rides at reduced capacity just made things worse. And when Covid and staffing shortages led to much steeper cuts in shows, characters, entertainment, parades, and the like, the problem was made exponentially worse.
In the end, there are only two possible solutions. One is to reduce attendance. The other is to increase capacity by greatly expanding the number of rides and other forms of entertainment. Both would cost Disney a lot of money and reduce profits, at least in the short run. And therefore, neither is likely to happen--at least not under the current company leadership.
Another option is to come up with a way for the wealthier guests to buy a better experience (at the expense of the rest of the guests). I think we might see that coming. VIP tours already do that, but they are a relatively small piece of the puzzle. Some form of much higher priced line skipping---like a $600 express unlimited pass, or a la carte on-the-spot, instant Fastpasses (sorry, Lighting Lane experiences) priced between $10 for the lamest rides (tea cups, Muppetvision, etc.) and $50 for the top rides (RotR, FOP, etc.)---might provide a way to raise significant profits at very little cost to Disney. Which makes me think they will do it, even if they take a PR hit as a result. This doesn't solve the problem. It actually just makes it worse for everyone but the wealthiest guests. But money talks. In fact, these days, I'm not sure Disney speaks any other language.
