What can the installation of elevators in the construction of urban pedestrian overpasses reflect a city?

The installation of elevators on footbridges shows that footbridges are very important, and the cost of installing elevators should be borne by commercial stakeholders.

For example, businesses and restaurants around overpasses pay more taxes, which is enough to support the expenses of elevators.

It can be said that installing elevators in the construction of urban pedestrian bridges can reflect whether a city's tax revenue is sufficient.
