Driving people around is a marginally skilled luxury service that in theory a teenager with 1-3 years of personal driving experience could do. Heck, a 20 year old born and raised in an area can probably do it more competently than an older "more experienced" driver who hasn't lived in the area that long.
This is like the outrage that McDonalds workers, people who make $2 hamburgers, are the lowest men and women on the food industry totem poll in terms of wages. Forget automation; if your job is something that a 19 year old high school dropout who fits the stereotypes can do as competently as a "20 year veteran," you aren't going to make much money because the barrier to entry and value of experience is minimal.
It's like going back 100 years and complaining that "senior ditch digger" doesn't pay substantially more than "junior ditch digger."
