They get together to talk about how to make capitalism more profitable, though they refer to capitalism as "business." They view organized labor and government spending as their enemies. They oppose anything that gets in the way of the profitability of "business" generally (and also specifically, as in the case of policy developments that might reduce the profits of corporations in certain industries). They also oppose, generally speaking, anything that makes it more difficult for private individuals to accumulate massive amounts of money via capitalism–which in this instance they speak of as "investment."
They don't have to know or desire that the working class suffers. They just have to have a dogma that says that the less government regulations there are, the juster the world. The fact that this stance syncs up with what earns them more money (and, indeed, what allows them to live the lifestyles they live at all)–that doesn't have to be paid direct attention to. They can tell themselves that it's not about the money. They can tell themselves that capitalism is justice itself, so they do right indeed by enacting capitalism most fully–in practice, this means handing the state ever more fully over to the capitalist class, and, specifically, concentrating the power ever more fully into the hands of the very richest.
