The self-interest for the bureaucrat and representative is supposed to end at their remuneration including their handsome retirement options not shady side hustles and market manipulation at the cost of the collective.

In matters of collective concern fair and just rarely aligns with personal self-interest. Because no matter how good the outcome of any endeavour for the collective given a budget, it will be even better for select few than the entire collective. It is simple economics.

If you look at the outcome of highly corrupt states, you will see proliferation of Private Security, Collapsed education system, failed financial services and markets, not highly efficient systems in service of “self-interest of the administration”.
