Re: so why is it
Politicians (buying votes) with public money is responding to the needs of the people that elected them. Buying votes with personal wealth is usually for personal gain. And billionaires generally are rewarded big time because they get the most attention.
A good point recently was the public opinion polls on several issues which showed alot of public support on various issues. However, public opinion did not influence the decision making because the legislation was passed which was in direct disagreement with public opinion. Evidently big money was calling in their chips.
