The Starship Troopers movie was self aware - the writer-director combo also worked on Robocop and that is pretty unambiguous about regulatory/corporate capture and malfeasance.
The book however… Heinlein was a weird political mix of right winger who had an open mind about hippies, but he uncritically promoted a militaristic society as a virtue, a permanent junta as a normal thing, and absolutely brushed up to fascism.
