You’re not getting $4 lunch bowls in Seattle when minimum wage is more than $20/hr. You aren’t getting affordable anything when labor is so expensive. (You also aren’t getting your 16 year old their first job either when labor costs more than your kid is worth but that is another topic entirely)
Zoning is only one tiny piece of the puzzle.
The labor is expensive because the rent is expensive.
Guess why the rent is expensive?
