This is becoming a circular argument. WDW does have a paid options, but they also have a DAS which is NOT a paid option. The complaint is that those who have paid are allegedly being delayed getting on attractions by those who have not paid for a similar option, especially since many guests have lied/exaggerated to gain the similar, free option.
The arguments have been about how to fix this problem without having a negative impact on either group, while also not having an even more negative impact on guests who, for whatever reason, cannot or will not pay extra.
An express pass only works if a small % of guests have one. When the majority of guests have them - or something very similar - not only does it make the waits longer for those who do not have them, but also for those who have paid to have them. It then lowers the value of having one.
If there were more attractions, or the # of park guests decreased, or the number of guests allowed to purchase Genie+ & LL were capped, along with limiting the # of DAS users per day, it would help.
Only the first solution would make everyone happy.
