When San Diego’s population and economy grow, it significantly affects how well the city provides its residents with basic services like emergency responses and functional roads. The Rebuild San Diego ballot measure proposed by the city of San Diego pays no attention to this fact.
Inflation, or price rate increases, makes it so the city gets less out of each dollar it spends, either in materials, like cement or fuel; or labor, like salaries or benefits.
On the other hand, population or economic growth rate increases, increase city expenditures because they create the demand for the city to purchase more materials or labor to keep service levels even. If there are more people calling 911, there will be a need for more dispatchers, police-officers, EMTs and vehicle maintenance crews. This service demand from growth happens regardless of inflation.
