Since Uber is an on-demand service, and the driver availability can fluctuate moment-by-moment, their pricing serves as an incentive.

Wendy's could change they pay scale to reward efficient work during peak hours, but otherwise, it makes no sense. The cost and availability of their food doesn't fluctuate moment to moment, so the disconnect in prices just doesn't make sense unless it goes to labor.

Nowever, as more and more states are changing labor laws and wages, and workers often demand higher pay as inflation pressures mount, and costs also rise due to inflation, I can see how the corporation might be looking for ways to boost earnings to meet those demands and pressures without the psychological effects of changing the "base price" of their food.

But even trying to make every excuse I can, I still don't believe this is a viable model. Customer backlash is likely to be severe.
