Lachmann has developed elite-conflict theory in, for example, earlier works like Capitalists in Spirit of Themselves, and From Manor to Market. In those books, as in this one, Lachmann mobilizes and develops elite-conflict theory to explain large-scale political outcomes. But this most recent book is not really about exploring the possible dimensions and contours of elite-conflict theory as much as it is about explaining imperial decline in general and US imperial decline in particular. 

That balance between the general and particular is interesting because for a lot of readers there is going to be some implicit tension between how they feel about the current situation in the US and the idea of the end of US imperial ambitions. On the one hand, we might be ambivalent or even vaguely pleased about the end of an empire but simultaneously sad about the potentially disastrous way that era is winding down in the US.
