It all comes down to supply and demand. There will always be demand for escorts, but are their prices coming down? Ultimately, it comes down to where you're looking. Back page escorts are notorious for being insanely cheap. Most times, you do get what you pay for. Women that are with several guys a day, with a huge risk of STDs. You do find some diamonds in the rough, but you have to do some serious homework.
When I say homework, I don't mean read her ad and gawk at her images & services. Review the escort thoroughly. There's a reason cheap escorts are charging less for services. There are so many escort on back page nowadays that they are competing against each other.
Don't get me wrong, a hobbyist loves getting a girl to do X for a dollar amount. At the end of the day though, is it worth the STD risk? I mean, is it?
Back page now no longer accepts credit cards. So what's left are girls that use pimps (Basically) to manage their ad postings. I mean, how many escorts do you know how to use Bitcoin? Or write a check for credits. Yea, exactly. Most of these cheap escorts on Backpage aren't even the ones posting their ads.
Again, there are some that do it themselves, but it's such a small percentage nowadays.
I've said it before and I continue saying it, avoid escorts. Try matching up with girls that are looking for mutually beneficial arrangements on sites like Arrangement finders.
