There’s a lot of politics involved. All the students want to take CS classes because they understand it can be a path to a high lying career. This leaves other less popular departments scraping to justify their existence. Basically the gap in demand is huge, but the gap in funding can never be proportionate because it would mean other departments barely get anything. So the CS department is perpetually underfunded, but e.g. the philosophy department probably has more money than it really needs based on natural demand (demand is artificially propped up by required courses)
