The two things that truely turned the hobby against the HDH and their presumed exclusive ownership attitude towards the hobby and being able to tease guys for top dollar and provide minimum service was the onset of Viagra and Internet. The internet has especially opened the door for more mass marketing of providers in every market and as the economy gets tougher and jobs harder to find you will see more and more hot 20 somethings out of college trading their personal talents for a living after all the law of supply and demand never changes, if side by side one provider looks, services, and interacts just as well as one charging $200 more she will get the action as long as she maintains her service.
Before Viagra and the internet, generally you had these old wealthy businessmen with more money than looks, appeal, and sexual ability. They were willing to pay a hot secretary, or female sales rep $400-1000 just for a evening out, which was basically dinner out, maybe drinks at a exclusive club where the guy could build his esteem by showing off to his colleagues his hot young arm candy, if anything sexual was involved it was generally a blow job, and it probably did not have to be a very good one because the guy probably popped just watching the back of this hot young things head go down into his lap, and he was finished.
Then along came viagra, now not only could sugar daddy lick the jar, but he could once again stir the pot like he use to when he was 20 or so years younger. These so called HDH that were use to getting paid $400-$1000 to go out and eat at top dollar steak houses and exclusive clubs for the evening now was faced with a big hard cock at the end of the evening that was not going down until papa got everything he wanted, and by god why shouldn't he after all he has paid this chick 4 times what her regular salary as a secretary is for a week for just a 4 hour evening. Then being businessmen with access to computers and the internet they started seeing sites like ASPD, EROS, craigslist, backpage etc. They started seeing girls way hotter than his 36 year old secretary offering a evening out topped by a PSE for $500-600 dollars. They started seeing all of these hot college cheerleader and playboy bunnie types offering over night dates for the same thing he was paying his secretary that gave a lame ass blowjob.
