We're concatenating all the different roles and responsibilities of councils here. It's not entirely fair to tar all of them with the same brush.
Note that town councillors are not civil servants, but unpaid volunteers. Admittedly, they get expenses for their work, but essentially they are acting in person, not as employees. Civil servants by contrast are employees who work for central government, not local.
And town councils are not usually responsible for waste collection or planning, either.
