We've just lived through an example of what happens when some people have more control over the economy than others. One person one vote works better for me than one dollar one vote. Boom and bust are baked into the capitalist cake, and giving the richest capitalists control over regulations designed to protect the majority from financial predators only ensures greater economic inequality for future generations.I often see posts here intimating that it's wrong for some people to have more economic power than others. You seem to be applying the basic premise of democracy - one person/one vote - to economic relations, and I think that's a mistake.
Regardless of what we just lived through (I'd argue that it's most often state policy, or more accurately, ill-considered manipulation of state policy, that triggers market failures) applying democracy to our economic decisions is tantamount to totalitarian government in my view. Government power should be limited, ideally by a concise constitution, to those situations where coercive force is actually necessary. Nearly every decision we make can be characterized as 'economic' in nature, and I don't want to see government wield such a pervasive power over individual decisions.
