I posted the statistics. I can see only one 6 month period in the last 11 years where prices were lower at the end of the period, than at the start, and this was following the great financial recession. And as pointed out, the car market is highly sensitive to supply side issues.
But, ok, I'll use you example of the car market. Since 2011 prices have doubled, if you take the statistic of one drop, you have to accept the overall trend, and that is the trend.
Escort prices around 2011 seem to have been around £120 p/h. So if we use YOUR demonstrated market to issue a point on pricing trend, then actually you are stating escort prices priced in your market are actually lower than they should be.
I.e. punters should now on average be paying £240 an hour based on your car market example.
This simply reinforces my original point, escort prices have been stable or lower than many other markets during the last 10 years. It's your example, that is what your example shows, does it not?
So if your serious point is you'd want a few short term price drops, but on the longer trend are happy to see prices double, I'd question that logic. We need stable pricing in the economy.
