I'm not really sure what you're trying to say, are the democrats not friendly with ANY big businesses? Is the extreme right wing of US conservatives not motivated by money (Donald Trump is often thought of as a successful venture capitalist, the amount of money funneled out during his presidency, etc...)?

Russia is one of the most inequal countries in the world in terms of wealth distribution, and for decades now oligarchs in Russia have gone hand in hand with the state in eroding any form of democracy and exploiting what freedom those citizens do have.

So, can you really say democracy can exist with money?
