Low tax advocates want a more streamlined government that looks after core functions (managing trash, police, etc) rather than what it has taken on today (entire multimillion dollar agencies tasked with getting more women into high status jobs, regulation of the size and shape of cabbages, etc)
The idea that "people who want less tax than I do just crave widespread poverty" is a sign you have an ideological brainworm. No one thinks like that.
