Welcome back after all these years !
If we look back at the average price of hotel girls 3 years ago you will find the average price was $700 - $800, now days they are $800 - $900 ... about a 15% increase
over the same 3 years, average price of walk ups have gone from $350 - $380 to $400 ... 10% increase
over the same period of time the average salary of a blue collar worker have gone up 25% - 30%, white collar maybe increased by same amount
bearing in mind there are few girls with HKIDs wanting to become WGs and as existing WGs gets older, walk up prices have remained relatively stable
you may see a change in the HG scene over the next few years but their prices have so far remained pretty much stable
for the Singapore scene, I think one of the things you need to look at is where the HGs are from
