This is issue of representative democracy, by design. Representatives, sometimes have too wide rights and have not strong enough constraints, hoping, elections will choose very good guy, who will use his opportunities wisely. But unfortunately, in real world, exists deficit of good leaders, and it is much worse on local govt level, because this is like second league (supreme league are govt of country, country parliament, top scientific organizations, military tops, and tops of top corporations).
