Communities have to show that

they care enough about their members and that they are resourceful and responsible enough to do without government intervention. They have to leave government with nothing to do. Of course this works against the interests of politicians who look for a career in being important and against the interests of political parties which have built a political ideology around their corporate identity and who desire to convert others and to impose their ideology on others.
Noblesse oblige works well in the USA where there are so many institutes for the betterment of the community. Australia has some community spirited noblesse oblige but we are a new money country and new money is less generous than old money.
