Small countries, like mine (.pt), kind of disprove this idyllic vision of small government. Small governments easily fall prey to large multinationals.

USA's woes with oligopolies may have many causes. A government concentrated at the federal level isn't probably one of them.

My rebuttal would be that the oligopolies exist in heavily regulated areas (health, banking, telecom), and that isn't a coincidence. You don't need a big government to protect yourself from multinationals, you need a non corrupt government.
