How does a Political Entity acquire control over an Economy?

How does a Political entity acquire Control over its Economy? In other words, how does a Democracy acquire Control over Capitalism? The word 'Control' is not a very good term. It implies some kind of 'Power' to give 'direction' to 'Economic Activity'. That's not 'possible'; its not 'permissible' in a Democracy. Economic Activity is a 'pure' Corporate activity, but so is Democratic Activity. Hence, the Two activities are Autonomous. Democracy can 'allow' the passage of Laws to 'create' Corporations and to give some sort of 'direction' to Corporate activity. It does this by passage of 'Articles of Incorporation' and establishing 'Corporate Law'. Hence the 'Business Entity' exists within the 'Social' of the Political Entity. Of course, the Law considers the 'Corporate Nature' as a 'Person' in 'Contemplation of Law' within the protection of the 'Constitution'. Hence its 'Person-ality' is considered as a 'Legal Fiction'. Of course, a Fiction is a Fiction, no matter how you 'wrap' it. A Democratic Political Entity is a 'Real Entity' 'constituted' by the Real 'People' it purports to Govern. Hence, its a 'Written Constitution' and any Human Being can read it; study it; and acquire 'knowledge' of 'Constitutional' Law and 'Democratic activity'. The Highest Court in the Land chose to protect the 'Nature' of the 'Corporate Fiction', but it did not give it any 'control' or 'Power' 'over' the 'Political Entity' that Governs the 'Social' in the 'Nation'. Hence, most CEO's are very knowledgeable about 'Capitalism' or 'Business Principles' which 'motor' a Business Entity. But, that does not mean they have knowledge of the 'kind of thinking' that can 'motor' a Democracy: that requires 'Democratic Political Thinking'. Hence, a Political Entity cannot control its Economy but it can require knowledge of democratic Political Activity that allows its Economy to function within a Democratic Social. It can require that all Candidates for Higher Office, be qualified to 'Motor' a Political Entity. Sure, anyone can Run, but why Run if your only interested in 'Economic Activity' and not 'Democratic Activity; or why Run if your qualifications are only 'having lots of Money'? We need 'Real Politicians'; and, 'Political Knowledge' of Democracy should be a 'requirement' for 'eligibility'. If Candidates do not have knowledge of Democracy, they should not be allowed to Run. We do not need 'CEO's' at the 'Political Helm'; nor Dictatorial Principles; nor 'Politically Correct' Politicians; we need 'Real Politicians'. Where are the Real Politicians?
