How do you make a group?

How does the Carlyle Group, the investment firm, make revenue?

• I'm watching the film Fahrenheit 9-11 by Michael Moore. The movie states that the Carlyle Group, an investment firm that invested in national defense, stood to gain from the Sept 11th attacks via their investments in a subsidiary United Defense (at least I think this is what the film is saying). What is it saying about the relationship between the Carlyle Group and United Defense? How does the Carlye Group make money from investing in defense? Does it make profit because United Defense makes a profit by making weapons for the military, which wealth is spread to the Carlyle Group because United Defense is essentially borrowing money from the Carlyle Group?

• Answer:

  Carlyle Group which is an investment partnership use to own United Defense. United Defense makes military equipment. Since Carlyle Group owned United Defense they were entitled to the profits from United. United Defense is owned by BAE Systems Land & Armaments now.
