General consensus is the market is saturated with drivers. Right now it's very slow because UK is out of session. This is actually a good thing because it will rid the market of drivers. However, when the college students return it's expected to pick up.
Regarding harassment, I personally haven't had any issues. From some of the messages boards, it appears the drivers are encouraged by the Police because they view them as beneficial to reduce the DUI problems. Airport is welcoming and their police don't hassle the waiting drivers. Taxis are okay, there are a few that spout off but it's not a regular problem.
I did hear that LexTran, the local bus company is hiring at a little over $20 an hour. They will pay to train you to get your CDL. Of course Amazon is an option as well but much lower.
Hope this helps!
