think about this like the pyramid, the higher tiers it goes, the lesser pieces of bricks it has.
there won't be everyone charging super premium prices, there won't be enough customers to support them.
lets take Chicken rice for an example,
many people like to eat chicken rice,
you can find $2.50 at most places neighbourhood hawker centres or factory canteens, they provide the most simple dish, noting fancy
you can find $1.00 chicken rice from time to time, but you may have to order two to three plates to fill your stomach
those sell chicken rice at air-con food courts, price start from $3.50, some offer set set meal at $5.50 or more
and some restaurants specialise sell chicken rice only, their simple set start $7.50
and 5 stars hotels do sell chicken rice too, their price noting less then $20.00.
if you (customers) like to have chicken rice (engage photography service),
you (customers) will pick where to eat (hiring photographer), what kind of chicken rice dish (spending on photography services) base on your (their) budget,
we can have our favour chicken rice at many places,
and we should have some realistic expectation of a gourmet chicken rice set won't sell for $2.00.
