Reader says parking meters were a foolish proposition

As a resident since 1969 I always said the meters were a foolish proposition. I’d be interested in th actual numbers of revenue , minus costs of meters , salaries of meters workers etc (less coin boy theft ). Simple solution …eliminate meters. Double th overtime parking fines. Meter maids can chalk the tires to enforce the overtime, or more likely today there is a video cam app for them to use. Make it a triple fine when a store employee gets caught wiping the chalk off their tires. I refuse to pay a meter to use th post office
