Why are you making assumptions about the education level of Uber drivers? 15% of cab drivers in the US hold a bachelor's degree [1] and I'm sure that number will keep rising.

I've heard complaints about how increased competition with other drivers and slashing fares are causing driver's salary to dramatically decrease lately. I can't comment on the "average" driver salary however, it is a job that comes with some serious caveats, which is the territory of being an independent contractor - so because of that real salary is significantly lower than that of employees making the equivalent.

this may be of interest
