I don't see where he's agreeing with Moore except that they both want to get out of Iraq and Afghanistan.
I don't know what message of current Republicans embraces Corporatism. I don't know exactly what you mean by Corporatism.
Corporatism as defined by Paul seems to mean where corporations influence the government to short circuit free markets. If that's the definition I agree 100% it's a bad thing - that's hardly Moore's position though. Blocking free markets applies far more to Democrats obviously. For example opposing free trade. Obama just came out with a tariff on imported cheap tires from China. It was a pure payoff to unions that will hurt lower income Americans. It may also put lots of small discount tire distributors out of business.
Preventing utilities from competing with each other is another example - it's mainly Democrats who do that.
Pelosi, Reid and company won't consider mandating that health insurers can sell policies in every state in their "reform" bills (calling them reform bills is Orwellian IMO). Many states allow only a few insurers to sell health policies. Most states also mandate that any policy cover all sorts of things. It's mainly Democrats that put those mandates in there. The list goes on and on.
I also don't know what's meant by "embracing the military-industrial" complex. Paul's example in the video is using contractors instead of troops. If you mean we invaded Iraq/Afghanistan in order to benefit defense contractors, that's out in the twilight zone with the 9/11 Truthers.
Moore's statement that the top 1% have more wealth than the bottom 95% is another of his many fabrications, like his lies in Fahrenheit 9/11.
