The price of everything in ancient times was affordable for the target group.
A samurai with deep pocket could buy nicer stuff than a poor samurai. Its the same like those days
It's like building houses today. Everyone complains that they can't afford a house, but they don't want to save and still want to afford a vacation and a car.
Our parents built large houses with high interest rates and low incomes. They didn't go on vacation but worked for their dream. And that's exactly how it is in all cultures from the Stone Age to today.
