What was Michael Moore's hypothesis in his film Capitalism: A Love Story? What was his research methodology? What were the techniques utilized in his research?

In Capitalism: A Love Story, Michael Moore hopes to sketch out the social, economic, and moral dangers of capitalism through his trademark sarcasm and guerilla filmmaking. The film is almost essay-like in structure, with Moore crafting a clear thesis of why he believes capitalism to be inherently more dangerous than something like socialism.
Moore begins the film by taking a look at when America was, well, "great." In the 1950s, the top tax rate was a staggering 90 percent, which allowed the country to rebuild and progress after a detrimental war. Unions were pervasive in American life, and working conditions were often ideal. College was cheap, if not free, and Americans had the opportunity to better their lives and their entire society without risking massive debt.
Moore then suggests this era to end quickly and harshly in the 60s, 70s, and 80s, when big banks took over during the Reagan administration. In a convincing proposed theory, Moore shows evidence to suggest that the Merrill Lynch chairman Donald Regan (not related to President Reagan) helped convince the president to dismantle unions and completely change the industrial infrastructure. The top tax rate was dropped drastically, production spiked exponentially, while wages stayed frozen, and depression and anxiety consequently skyrocketed.
Moore's insistence on using factual-based evidence helps make his case quite convincing. Yet, it wouldn't be a Michael Moore film without his clever sarcasm, and so, later on, Moore makes the film far more interesting and memorable by attempting to place those on Wall Street (and those guilty in being involved in the big bank bail-out of late 2008) under citizen's arrest. His point is simple: these men and women are literally criminals that get to avoid punishment, due to our unique economic/political system.
Moore also plays upon logic by asking religious figures whether or not Jesus Christ would be a capitalist. These figures all suggest that Christ, of course, would not be, and Moore pays specific attention to one quote attributed to Christ: "It is easier for a camel to fit through an eye of a needle than it is for a rich man to get into heaven."
Lastly, Moore uses emotion to convince the viewer by interviewing many people whom he considers to be victims of capitalism: commercial jet pilots (who make next to nothing salary-wise), blue-collar folk who lost their homes to merciless bank foreclosures, and juvenile youth who are abused in a bizarre "for-profit" youth correction facility. This is what is perhaps the most convincing method of Moore's research, for it plays upon human empathy. He shows the viewers how, while many may be succeeding, there are many more who struggle, and it is up to the viewers to make a difference in helping them out.
