I think you might have misunderstood the point I was making. What I implied was that for a society to be free from authoritarianism and under democratic control, there also has to be some limits to the power wielded by the rich. Of course one could try to limit the power of money, but I think the most important thing one should do is limit the mechanics of the economy that allow for unlimited accumulation of wealth (i.e. read taxes and worker collectives).
