But this is exactly what I mean. You can try to make the job and the company sound appealing to females and minorities. But let's say 99.9% of the population around you is white and you just don't happen to get any female candidates applying because the number of females with those skills that are currently looking for work in your area happens to be zero. You could do a bunch of footwork and ask lots of "why". But if your small-to-medium sized company chiefly want to execute on a specific business goal, their focus will be on shipping product, beating the competition, keeping customers and employees happy. Who has pockets deep enough to fix some broader societal problem? How much of the budget should they spend on that? Is it even their obligation? What do the investors think?

This type of wider social problem should be tackled and funded by government: any department with a role in employment, equality etc. Responsibility for social issues cannot be left to private, profit-driven companies.
