I don't see an increase at all. Supply is at all an all time low since 2016.
Yeah - there's often a double movement with these kind of things.
Some women not suited to sex work are going feel forced to enter the trade out of desperation.
But unless an economic squeeze is so extreme it makes a country a total basketcase (as normally only happens in the developing world) - then the desperate new WGs can be outnumbered by lasses leaving or not entering the industry due to lack of Punters spending cash.
It's like in the J Lo movie Hustlers. After the 2008 Lehman crash, there were much less rich guys spending cash on sex work, so the lasses left the strip clubs & moved on to different types of hustle. Or to give a real life example, I used to go to the same town every year in Spain as we had a mate living their with a villa. Normally, there would always be 2-8 outdoor WGs on the roundabouts in the town centre. But when we visited in 2012, there were none. According to the guy who lived there, it was nothing to do with enforcement, but all about punters not having cash to spend thanks to the 2012 Spanish recession. The same clubs (Spanish name for brothels) were still open, just with less WGs & punters.
That said, I've not noticed any reduction in the supply of WGs here in London, so I'd guess it's region dependent.
