Whether pizza is still a cheap food
Pizza's identity as affordable food is historically accurate and increasingly strained. The same city can sustain a dollar slice and a £16 certified Neapolitan pizza; whether pizza is cheap now depends entirely on which trade you mean, and the generalisation is made in both directions.
What kind of claim this is
Disputed or contested
Claimed only at this scope, not beyond it. How PizzaHQ scopes cultural claims
Where: Multiple
Most sharply visible in New York and London, where both ends coexist.
Why this is disputed
Both 'pizza is still the cheapest way to feed a group' and 'pizza has become expensive' are commonly asserted and both are supportable, because they describe different segments of the same trade. PizzaHQ records the split without picking a side.
