Maybe I'm overindexing on "they steer" and "effective strategy" - it still reads that this group has way more control and deliberate planning than they do.
And, "implicit, uncoordinated conspiracy" is an oxymoron. The word "conspiracy" has a definition.
If all you are saying is "sometimes billionaires are aligned" - sure. Sometimes politicians are aligned. Sometimes teammates are aligned. If one wants a platitude with some predictive power "people are self interested" is going to work more often.
“People are self interested” works fine as long as you extend the analysis to include the class dimension. People in a specific class are generally going to advocate on behalf of that class, because it benefits them to do so. No conspiracy needed.
