You can fire them. Differentiating between a cleaning of house and heartless cutting of services, however, is difficult.
Quite the dichotomy you've established. Cutting of services is automatically 'heartless'? As they are always useful, necessary, and better than alternatives... while cleaning house to replace them with another set of politicians with the same prerogative is the 'good' solution?
Context matters. Neither are automatically better solutions, nor is chopping services necessarily 'heartless'.
