The follow text provides some context to what you are saying. You can use the phrase "industrial complex" with the term "monopolies", interchangeably:

"It is more realistic to view U.S. economic and foreign policy in terms of the military-industrial complex, the oil and gas (and mining) complex, and the banking and real estate complex than in terms of the political policy of Republicans and Democrats. The key senators and congressional representatives do not represent their states and districts as much as the economic and financial interests of their major political campaign contributors. A Venn diagram would show that in today’s post-Citizens United world, U.S. politicians represent their campaign contributors, not voters. And these contributors fall basically into three main blocs."

The fight over Ukraine, global hegemony, all of that, is about maintenance of the monopolies, or if you will, an undeclared monarchy.
