Your efforts to minimize the overwhelming impact of lobbying money, and to excuse it as necessary for survival, betray one of two things: a conflict of interest on the subject, or deep deep deep deep deep ignorance of just how completely the systematic bribery of “lobbying” has corrupted every facet of government.
Care to tell me which is your particular affliction here?
Neither. The most influential force on government is the federal workers union which accounts for millions of votes. It isn’t so much that money buys influence for any specific industry, but the votes that organizations like unions, welfare recipients and the like carry.
