Further explanation is required, because to the extent that the ruling class controls the government - pretty completely - government spending must be directed towards its interests and desires and it would have no conflict with it. There is no reason, inherent in their situation, for which large capitalists and their entourages should dislike a powerful government and large government expenditures.
On the other hand, percipient working- and lower-middle-class people would be aware that it was they, and not the rich, who pay for the expenditures of the government. This awareness might dampen their enthusiasm even for programs from which they might be imagined to benefit, and certainly for those from which others benefited.
