Why is the 'Business Corporation' the most Protected 'Person' in the World?

The 'Business Corporation' has been 'Christened' as a "A Person in Contemplation of Law" and which is also recognized as a "Legal Fiction". 'Everyone knows' that a 'Fiction', whether 'Legal' or 'not' is not 'anything Real'. So why does the Law have 'Fictions' and why does it protect the Business Corporation. I do not think that 'Law in General' is held together by legal Fictions when it comes to personal Liberties or Personal Rights of the Individuals in the Social. Most of those Rights and protections are justifiable by the 'Freedom and Equality' that 'inheres' in the 'Human Condition'. It seems like 'Legal Fictions' have become 'necessary' to hold 'Legal Argumentation' and 'Justification' for some, specific line of 'Legal Reasoning' and 'Legal Argument'. Why have certain Legal Fictions become necessary? Of course, its understood that some 'Social Entities' and more important, 'Social Values' have become so necessary that 'couching argumentation' in the 'Fictional Mode' is one manner of protecting the 'Concept'. But, why in the Economy? Why is the focus of the 'Protection of the Corporation' relate to its 'Size and Monopolizing' effect of the business? Of course, the Economy needs to be protected, but why do the Fictional Aspects also relate to 'Money', lots of Money? Do they all have to be in a 'Race' to be on the 'Forbes List'? Of course, the Economy is about Money but its also about the Freedom and Equality of the Real Individuals at the Bottom. The Bottom needs an Economy and the competition between Individuals is a good measure of a succesful Economy. But, the Business Corporation is a Fiction; a Fiction whose Productivity is the result of a functioning that's Autocratic in its results. Why can't it be a Democratic Fiction that 'requires' every Business Corporation to have a Department for Democratic Activity? Why do Democracys create 'Autocratic', 'Economic Institions' that establihes an 'Unbalanced' and 'lopsided Economy'. They 'benefit' the 'Rich' and contributes to a 'bigger Gap' between the 'Haves' and the 'Have-nots'.
