Whenever I get a date of 4 hours or longer, it is specifically because the gent enjoys talking with me. These days, the vast majority of my income comes from extended dates, overnights and trips with hobbyists. I think this has little to do with what I learned in college and everything to do how a particular client clicks with my individual personality. However, I think many of them may never have pulled the trigger in the first place if they didn't know I'd graduated from college. This is an unfortunate bias as I have met many brilliant women who've never finished school--and we all know that there are plenty of morons who somehow managed to earn degrees.
There is one local provider who is virtually illiterate but manages to get an insane amount of money per hour pretending to be a college graduate. She seems to get away with it so it makes me wonder why more ladies don't fake it. And no, she doesn't post in threads on eccie. All of the eccie ladies I know are honest about their education.
BTW, I participated in this survey but it was when I was a brand new provider and was only getting one and two hour dates.
