Because they're small programs that aren't missed by most. And the rule of thumb that humanities and social science programs subsidize sciences seems a bit misleading. There are an enormous amount of other funding sources within the American system (federal government, industry, military) that patronize science programs. There isn't a comparable system on the other pillar of the academy.
