Beg to differ.
It is big government itself that has corrupted the process.
Corporations and interest groups spend big money on lobbyists and campaign contributions as a matter of self-defense. Simply put, the government has the power to destroy them. Or, alternatively, to richly reward them.
Take these powers away from government...and big corporate budgets for lobbying, etc. would shrink to a fraction of their current size.
Limited government is innately less prone to corruption than big government.
Their major stockholders are another matter.
Well said, and a fact that is routinely ignored during the overall discussion.
A primary reason that the Framers wanted such a minimal central government was so that it would be less likely to become corrupt or tyrannical regardless of which faction holds political power at any given moment in time.
