Corporate monopolies can only exist through government intervention. Government ‘assistance’ can include corporate welfare subsidies, tax breaks, insider contract deals that eliminate competition, crooked kangaroo court rulings and government regulations.
An example of government regulations that exclude competition are contracts that have very narrow requirements so only the favored corporations fit the criteria. Another trick that is used to prop up corporate monopolies is the federal permitting process that may absolve corporations from accountability.
The commerce clause is the most common excuse that the federal government uses to foist unsafe or unnecessary regulations on the States and the People.
Simply put, the commerce clause was created to keep trade flowing and to prevent tariffs on trade between the states. Over time, the federal government usurped power from the states and and now controls commerce, which means that they have control over everything that may cross state lines.
You can view a full constitutional explanation from Judge Napolitano about how the commerce clause has been distorted.
Under the Tenth Amendment States’ Rights, states can do anything they want as long as it is not a power that is:
• Delegated to the federal government in the Constitution
• Prohibited to the states by the Constitution
• Prohibited to the state by its own constitution
