If Capitalism is not 'democratic', why mix the two principles?

Democracy is one 'thing', Capitalism is another. If the basis of their proper functioning is not the same principle, then why mix the two. But, be careful; I'm not saying that the two cannot exist side-by side. For sure, they can both exist in a Democracy but, proper 'separation' is essential because democracy functions on the basis of the Freedom and Equality of each individual and Capitalism functions on the basis of 'making profits'. Government must be democratic, while the economy must be 'profitable'. So, what is the problematic? The problematic is 'greed' and the hoarding of the 'medium of exchange'. Money should not 'creep' into politics and democracy should not be 'practiced' for the purpose of making a 'profit'; nor, should seeking political Office be considered as a 'profit venture'. When money seeps into politics, the buying and selling of political offices becomes possible. If only the 'rich' can run for Office, we have the same effect. If money is hoarded, the 'medium of exchange' is not being exchanged. The hoarding of the medium of exchange is, obviously, why we have a 1%. So, how are the two principles kept separate? We have said that the problem is 'greed'. Greed is not a characteristic of the political, and it is not a characteristic of the 'proper functioning' of the economy. I say, 'proper functioning' because the 'medium of exchange' must circulate and not be hoarded. 'Hoarding' is even bad for the economy, because it fixates 'profits' in one place and stifles circulation; e.g. the 1%. Hence, money should circulate among the economy at the Bottom of government where all the People live. The bottom line is that 'greed' is a 'human problem'. Its not a political problem, nor, an economic problem. Its a human problem and the 'distorted vision' that 'more and more profits' is essential to living a democratic life of Freedom and Equality. Don't get me wrong; money is essential in both Capitalism and Democracy, but 'hoarding' is not, and democracy is not just for the 'rich'. ( That would be a Plutocracy) Government can get involved in 'helping' the circulation of money; but, the economy cannot 'define' the political. The goal of economics involves the 'use of money'. The goal of democracy, is the Freedom and equality of each individual. The government has a duty to 'govern' the Many; the economy has a duty to make profits. But, keep them separate. Human greed is a 'complete misuse' of the 'instinct' to possess. The 'instinct' to possess means to possess 'life' in Freedom and Equality, more and more life; every human wants 'life', and wants it, for as long as possible. More and more 'economic possessions' and 'greed' reverses the natural energies of 'life'. 'Pace yourself'. We live 'upside down'. Don't turn democracy 'upside down'.
