Quoted from irobot:Sellers cannot "push a market up."
The only way that sellers can push the market is if they ALL make an agreement to jack prices and restrict supply.
BUYERS and SELLERS set prices. Not one or the other
Your model assumes educated buyers and constraint.
Pinball is in a boom - so both of those things are lost. New money floods in without knowing what the trend has been... so they overpay. Next guy sees the 'market set' at those overpaid prices... and the cycle continues. Then, the sellers can easily take advantage as the educated buyers are outpaced by over eager or uneducated buyers.
The 'pure market' model is not so clean when you have long distance buying, fresh money, and lack of knowledge. It's prime for sellers to push prices up and still get the price.
