I don't shop as shi** Walmart selling Chinese-made crap and I buy certified organic, which typically does not use cheap labor from :"illegals" I choose to pay more for a number of things.
In a free market, consumers choose where to shop and how much to spend, with many choosing the mid-range price others the low, and others the high for the benefits and quality. And many people buying low-price goods do so because of a limited budget, they would love to be able to afford the better quality the higher prices buys.
A professional service like appraisal is not a mass-market consumer good ad it is not a store. And this is not about prices either, because with an AMC skimming off the fee, the consumer does not pay less, the AMC functions more like a mafia protection racket skimming fee as a way to get awarded an order
I am not even blaming just the AMC's, but the whole system that supports the awful way appraisers get their fees impacted by them.
