Is it too demanding for a Politician to be 'Altruistic'? Why do we have Politicians?

Is it demanding to much for Politicians to be Altruistic? What other 'motive' should a 'Public Official' have and why do we have Politicians? Politics is the most difficult discipline in the World because it requires a 'certain kind' of 'selflessness' and great efforts in the establishment of 'Social' and 'Political' Entities that benefits the 'Whole Bottom' viz. the real Individuals at the Bottom. That's the source of all 'Power' in a 'Democracy'. At the same time this discipline should benefit the 'Strength and Power' of the Political Entity as 'Political Entity' in the World. Of course, Political Offices 'earn' a pretty high Salary; they are not serving 'gratuitously'. Of course they won't get Rich from their Salary. But, if 'Service' in a Democracy, is not the Goal of a Politician, why not do something else? After all, Politics 'is a Service'. Certainly, one way to 'World Recognition' and 'Respect' is through Political Office. But, not all human 'motivations' are 'honest' and 'above board'. Here, of course, we could discuss different Political Systems and how they 'function'. Autocracies are expected to function as Autocracies. But, our concern is 'Democracy' in a Democracy. One very important 'factor' is not so much the 'Autocratic Attitude', in a Real political sense, but an honest 'Business Attitude', i.e., a motivation arising from having being a 'successful Businessman'. As we have already pointed out, the 'Business Engine' in 'Capitalism' is very 'different' from the 'Political Engine' in a Democracy. The Business Engine is energized by 'More and More of the same', or Money, or, if you like, Greed. But, the Political Engine in a Democracy is energized by the 'Freedom and Equality' of 'each and every' 'Real Individual' at the 'Bottom' of the 'Political Entity'. I say, 'Real Individual' at the 'Bottom', because I cannot include 'Corporations' that are 'Legal Fictions', 'not' 'Real Persons', and that received their 'protection' from the Supreme Court. Here, then is a Social Problem. A 'Real genuine attitude', arising 'from success' in 'Capitalistic Activity', imperceptibly, 'slipping into' Democratic Government as an 'Aspect of Freedom and Equality' of Real Individuals... a complete infusion of 'More and more of the same', or Greed, into the 'Social Fabric' of 'Freedom and Equality' of 'Real Human Beings'. A 'Genuine Political Motivation' of 'Freedom and Equality', 'overcome', 'inextricably', by 'Business Motivation', 'Greed', that leads us into a 'Social' that 'Divides' and 'Defines' us as 'Haves' and 'Have-nots'. The 'Sad' part is that the arising of the 'Haves' stems from the 'protection' of the 'Corporation' as a 'Legal Fiction' created by the 'Supreme Court. 'Surrealism' has truly taken over. Where are the Real Politicians?
