Economist: Markets work most efficiently without any government interference, since competition increases in free markets. Government regulation will never achieve its intended goal, since the most sophisticated corporations will always be able to game the system at the expense of the start-ups that are necessary to spur growth. Competition between corporations also forces those entities to self-regulate and it protects the interests of consumers. Politician: Unregulated markets are ripe for abuse. Under the current regulatory scheme, a handful of corporations dominate the marketplace. Vertical integration, under the umbrella of a larger corporation, expands a single corporation' s power across multiple economic sectors. We need to increase regulations to disrupt this integration and allow start-ups to compete on a level playing field. What is the main issue in dispute between the economist and politician? ['Increasing regulations will increase competitiveness.', "Competition is important for a nation's economic health.", "Corporations cannot be trusted to act in consumers' best interest.", 'Consolidating economic power in a handful of corporations is healthy.']
