This topic seems to come up every so often but shows an ignorance of basic cuntenomics.
If the demand reduces for any reason, the SP suppliers don’t shiver in some worn-out slippers and think they must reduce their prices. That would look cheap.
Where P = number of johns
I = income
R = going rate
P x R = I
Where P = 50 and I = 5000, then R = 100
If P = 40, I = 5000 but R = 125
They don’t reduce their income, silly: why would they do that?
