Powerful central governments run by two political parties that agree they should run a powerful central government is great for giant corporations and powerful special interests. They can pay the party leaders to get one of the most valuable agricultural products in history (hemp) morphed into a deadly weed (marijuana).
How much would commercial forest land owned by giant forest products corporations be worth if America's family farms were meeting a significant portion of America's fiber needs with commercial hemp? How much market share would oil companies lose if hemp based lubricants were allowed to compete with petroleum based lubricants?
How much would the U.S. Litigation Industry lose in lawyer fees if hemp were legal? How much would the U.S. Incarceration Industry lose in taxpayer funded government checks if hemp were legal?
Powerful political parties are not designed to protect the individual liberty and promote the private property rights of citizens. Non-partisan elections at all levels of government is the only conceivable way for a democracy to protect individual liberty and promote the private property rights of citizens. In a democracy, political parties should be lobbying organizations and nothing more.
democracies are not designed to protect individual liberties. The are collective in their nature. A democracy is two wolves and a sheep deciding what's for dinner.
